| === 2. Sicherstellen, dass in Zimbra keine Mails vorhanden sind === Einloggen mit dem Browser auf [[https://mail.desy.de|Zimbra]] und Suche dort nach Mailfoldern, in denen Mails vorhanden sind. Falls wichtige Mails vorhanden sind, diese sichern oder die Folder so umbenennen, dass es keine Namensgleicheit mit Foldern in Zeuthen gibt. Die Mails in Hamburg können bei der Mailmigration verloren gehen. Weiter mit Schritt 3 |
=== 2. Check that no mails are stored yet in Zimbra === Visit the URL [[https://mail.desy.de|Zimbra]] and search there for non empty mail folders. If folders with mails do exist, please save its contents or rename the mail folders such that there will be no name clash between folders in Zeuthen and folders in Zimbra. Under some circumstances existing mails in Zimbra can get lost when doing the mail migration. Go to step 3. |

| === 3. Mailmigration === Bitte '''auf einer schnellen Maschine einloggen''' (wgs, kein Desktop!!!). Falls kein wgs vorhanden, bitte den host 'transfer' benutzen. Windows User loggen sich über X-Win32 oder putty.ein. |
=== 3. Mail migration === Please '''login on a fast machine''' (work group server or host 'transfer', no desktop!!!). Windows users have to login there using X-Win32 or putty. Execute |

| Es erfolgt wenig Output, das Passwort (Zimbra-Hamburg) wird zweimal abgefragt, danach startet die Mailmigration, die nicht unterbrochen werden darf. Je nach Zahl der Mails und Folder kann die Mailmigration '''lange dauern''' (ca 10 Minuten pro GB an Mail). Fehlermeldungen können ignoriert werden. Der Fortschritt der Migration kann verfolgt werden. Das Skript ruft das Programm /products/admintools/scripts/mbsync auf, eine Manpage findet man auf /afs/ifh.de/user/f/friebel/public/mbsync.1 und /afs/ifh.de/user/f/friebel/public/mbsync.pdf |
The script does start with a password dialog (twice) for the Zimbra server. Then the mail migration takes place. This process must not be interrupted. Depending on the number of mails and the number of folders the migration step can take quite some time (approx. 10 minutes/GB). Error messages can be ignored. The progress of the migration is displayed with 3 counters. The script is based on the program mbsync (/products/admintools/scripts/mbsync). A man page for mbsync is on /afs/ifh.de/user/f/friebel/public/mbsync.1 and on /afs/ifh.de/user/f/friebel/public/mbsync.pdf |

| Die Mails werden nur nach Hamburg kopiert, nicht in Zeuthen gelöscht. Daher besteht in diesem Schritt keine Gefahr von Mailverlust. Nur nach erfolgreichem Abschluss der Migration darf Schritt 4 folgen |
The mails get copied to Zimbra only, they will not be deleted in Zeuthen. Therefore this step is safe and a loss of mails cannot happen. Do continue with step 4 only after successful completion of this procedure. |

| === 4. Löschen (gegebenenfalls Setzen) des Mail Forwardings in Zimbra === Einloggen in Zimbra, Einstellungen/Preferences auswählen, dann links den Punkt 'mail' wählen. Den Abschnitt 'Receiving Mail' suchen und dort das Feld 'Forward a copy to:' löschen. Wenn eine Weiterleitung der Mail nach ausserhalb erfolgen soll oder eine Kopie weitergeleitet werden soll muss stattdessen 'Forward a copy to:' ausgefüllt werden. Eventuell 'Don't keep a local copy of messages' ankreuzen. Die Änderung(en) bitte speichern! Weiter mit Punkt 5 |
=== 4. Delete (or set differently if needed) the mail forwardings in Zimbra === Login to Zimbra, select Preferences, then on the left side click on 'mail'. Look on the page for the section 'Receiving Mail' and delete there the field 'Forward a copy to:'. If a forwarding of all mails is wanted then that field has to be filled properly. Depending on whether a local copy should be retained or not the field 'Don't keep a local copy of messages' has to be set accordingly. Do not forget to save the changes! Go to step 5 |
| Line 49: | Line 38: |
| === 5. Umstellung der PEM in der Registry === Einloggen auf https://registry.desy.de/registry Auf 'Modify Person' die Suche nach der Person starten, ggf. die korrekte auswählen, dann das Feld 'Physical e-mail address' auf <accountname>@mail.desy.de, z.B. {{{friebel@mail.desy.de}}} ändern und dann auf 'save data' klicken. Spätestens 10..20 Minuten nach der PEM Änderung sollte das Mailrouting in Zeuthen so funktionieren, dass alle Mails zu Zimbra geleitet werden und keine neuen Mails mehr in Zeuthen ankommen. Weiter mit Schritt 6 |
=== 5. Changing ther PEM in the registry === Login to https://registry.desy.de/registry, choose 'Modify Person' and search for the correct person (i.e.yourself). If more than one result is displayed, select the correct one. Then change the field 'Physical e-mail address' to <accountname>@mail.desy.de, e.g. {{{friebel@mail.desy.de}}} and click on 'save data'. Do allow for 10..20 minutes after having changed the PEM. Then the mail routing in Zeuthen should work properly, i.e. all mails get redirected to Zimbra and no new mails will arrive in Zeuthen. Go to step 6 |
| Line 59: | Line 47: |
| === 6. Prüfen, ob neue Mails während der Migration in Zeuthen angekommen sind === Das geschieht einfach durch Wiederholung von Schritt 3. Achtung: es darf zwischenzeitlich keine Mail in Zeuthen gelöscht worden sein. Bei Verwendung von fast_mailsync dauert dieser Schritt in der Regel nur wenige Sekunden. |
=== 6. Check for newly arrived mails in Zeuthen during the mail migration === Simply repeat step 3. Important: no mails should have been deleted meanwhile in Zeuthen, as this delete would be propagated to Zimbra. This repeated synchronization should typically last for a few seconds only. |
| Line 64: | Line 51: |
| Wenn sichergestellt ist, dass alle Mails korrekt nach Hamburg transferiert wurden, kann optional Schritt 7 erfolgen |
If all mails have correctly been transferred to Zimbra, optionally step 7 can follow |
| Line 67: | Line 53: |
| === 7. Löschen der Mails in Zeuthen. === Achtung: Nach dem Löschen von Mails in Zeuthen darf Schritt 3 bzw. 6 nicht wiederholt werden, sonst droht Mailverlust. |
=== 7. Deleting the mails in Zeuthen === Important: after deleting mails in Zeuthen the migration step (3 and 6) must not be repeated, otherwise the delete will get synched to Zimbra and the mails would also be removed from Zimbra. |

| Damit ist die Mailmigration beendet und Mailempfang und Anzeige finden nun in Hamburg statt. Nun muss abschliessend noch die Umkonfigurierung aller benutzten Mailclients (auf Desktop, Laptop, Smartphone, ...) erfolgen. |
With this last step the migration procedure is complete. As from now on the Hamburg mail infrastructure gets used, all mail clients (on the desktop, laptops, cellphones, ...) have to be reconfigured |
| Line 75: | Line 59: |
| Dabei ist sowohl der Mailempfang (mail.desy.de) als auch der Mailversand (smtp-auth.desy.de) gemäss der Anleitung [[https://it.desy.de/dienste/e_mail/e206938/index_ger.html|im Web]] zu konfigurieren. |
For this procedure please follow the instructions [[https://it.desy.de/dienste/e_mail/e206938/index_ger.html|on the web]]. |
The following steps are required
1. Checking the contents of the PEM
The PEM can be found in the Registry under 'Modify Person' for each person in the field 'Physical e-mail address'
If the PEM contains mail.ifh.de or imap.ifh.de), then go to step 2. Otherwise no migration is required.
If the PEM does not point to Hamburg (does not contain desy.de), then only the mail routing has to be adapted (then goto step 4)
2. Check that no mails are stored yet in Zimbra
Visit the URL Zimbra and search there for non empty mail folders. If folders with mails do exist, please save its contents or rename the mail folders such that there will be no name clash between folders in Zeuthen and folders in Zimbra. Under some circumstances existing mails in Zimbra can get lost when doing the mail migration. Go to step 3.
3. Mail migration
Please login on a fast machine (work group server or host 'transfer', no desktop!!!). Windows users have to login there using X-Win32 or putty. Execute
/products/scripts/fast_mailsync
- The script does start with a password dialog (twice) for the Zimbra server. Then the mail migration takes place. This process must not be interrupted. Depending on the number of mails and the number of folders the migration step can take quite some time (approx. 10 minutes/GB). Error messages can be ignored. The progress of the migration is displayed with 3 counters. The script is based on the program mbsync (/products/admintools/scripts/mbsync). A man page for mbsync is on /afs/ifh.de/user/f/friebel/public/mbsync.1 and on /afs/ifh.de/user/f/friebel/public/mbsync.pdf The mails get copied to Zimbra only, they will not be deleted in Zeuthen. Therefore this step is safe and a loss of mails cannot happen. Do continue with step 4 only after successful completion of this procedure.
4. Delete (or set differently if needed) the mail forwardings in Zimbra
- Login to Zimbra, select Preferences, then on the left side click on 'mail'. Look on the page for the section 'Receiving Mail' and delete there the field 'Forward a copy to:'. If a forwarding of all mails is wanted then that field has to be filled properly. Depending on whether a local copy should be retained or not the field 'Don't keep a local copy of messages' has to be set accordingly. Do not forget to save the changes! Go to step 5
5. Changing ther PEM in the registry
Login to https://registry.desy.de/registry, choose 'Modify Person' and search for the correct person (i.e.yourself). If more than one result is displayed, select the correct one. Then change the field 'Physical e-mail address' to <accountname>@mail.desy.de, e.g. friebel@mail.desy.de and click on 'save data'. Do allow for 10..20 minutes after having changed the PEM. Then the mail routing in Zeuthen should work properly, i.e. all mails get redirected to Zimbra and no new mails will arrive in Zeuthen. Go to step 6
6. Check for newly arrived mails in Zeuthen during the mail migration
Simply repeat step 3. Important: no mails should have been deleted meanwhile in Zeuthen, as this delete would be propagated to Zimbra. This repeated synchronization should typically last for a few seconds only.
If all mails have correctly been transferred to Zimbra, optionally step 7 can follow
7. Deleting the mails in Zeuthen
Important: after deleting mails in Zeuthen the migration step (3 and 6) must not be repeated, otherwise the delete will get synched to Zimbra and the mails would also be removed from Zimbra.
With this last step the migration procedure is complete. As from now on the Hamburg mail infrastructure gets used, all mail clients (on the desktop, laptops, cellphones, ...) have to be reconfigured
For this procedure please follow the instructions on the web.
