we have an infrastructure with 3 UCS servers: 1. Primary (5.0-5e804), 2. Backup (5.0-5e804), 3. slave (4.4-9 e1371) with Kopano Mailserver (kopano-server-packages 22.214.171.124-0+ucs4.3~78.1), Kopano Webapp (126.96.36.199-1+173.1) and Z-Push.
Unfortunatelly every trial to upgrade 3. to ucs 5 failed - the server does not boot anymore when upgraded. We are stuck for some time now, currently there are also some errors, like missing items regarding Kopano in user administration, also user cannot be saved:
univentionFetchmailProtocol’ not allowed
We are thinking about reinstalling Kopano on a new server and are wondering:
- we need to uninstall the current Kopano first, since there cannot be 2 Installations in one domain as far as I know
- should we install directly a new USC 5 or 4.4 → reinstall kopano → upgrade to 5 → hope that it works?!
- should we restore by database and attachments OR do kopano-restore
(we have 33 stores, mostly small)
- what will be the effect for all Outlook clients and mobile devices when choosing each of the above?
Thanks in advance for your ideas and thought about this topic!
