How can we upgrade from:
Zextras Release 9.0.0_ZEXTRAS_20221203.RHEL8 FOSS edition.
==>
Zimbra 10 Network edition (licenced)
Server: Rocky8 with 16Gb RAM - 1 core 12 sockets RAID10
We have tried:
A.) Upgrading the version from 9 to 10. Zimbra didn't want to start properly after the update, not clear why. We puzzled 2 evenings with it. Reinstalled certificates etc etc.
B.) Migration tool in Zimbra 10 NE
==> fails at the mailbox data import (couldn't find any logs to see why)
C.) Using migrate "method 1" from Zextras:
https://community.zextras.com/migrate-z ... -method-1/
==> Also here it fails at the mailbox stage. All steps like account import etc without any trouble.
Though when updating the timeout most of the mailboxes seems to get imported:
Code: Select all
zmlocalconfig -e socket_so_timeout=3000000
Though some smaller mailboxes got "IO error java net connect errors", with these I can live with not to get imported. The most important mailboxes got imported with zmmailbox -z -m, including the biggest one all without any import errors.
Only it seems half of the mail is just not there after importing? The 40Gb zipfile contains all email between 2015 and 2023. When logging in into the webapp it shows only email from 2015 and 2016. The zip-file is build of sub-dir's per directory, some 500 mails per directory. INBOX1, INBOX2, INBOX3 etc.
Questions:
- It seems not all subdirs are being restored? Restoring took some 1,5-2 hour with the biggest mailbox.
- With this part of the zmmailbox command:
Code: Select all
"/?fmt=zip&resolve=skip"
- Any other thoughts with a different upgrade path to Zimbra 10 NE?
