I'm trying to upgrade our Zimbra installation from 4.5.7 GA to 5.0.6 GA (network edition) and am running into severe problems. I fortunately setup a test machine with the same OS version to restore a full backup and test the upgrade from there so we haven't lost any mail or functionality, but I need to get this to work so that we can actually upgrade our live install.
I keep getting ldap errors like the following during the upgrade:
ERROR: service.FAILURE (system failure: ZimbraLdapContext) (cause: javax.naming.AuthenticationException [LDAP: error code 49 - Invalid Credentials])
what then happens is that no matter what entries I fill in at the end it keeps not completeing as it claims there are items not completed. The only way to get out from that dialog is to use the q to quit.
The process I used is as follows:
* Install 4.5.7
* Restore full backup using the disaster recovery guide
* ensure 4.5.7 works (it always does, all messages there, accepts incoming mail etc)
* Start the 5.0.6 install
* errors occur
Interestingly an upgrade to 5.0.6 from a fresh install of 4.5.7 (no restore of backup) works fine. Is there a process to convert a 4.5.x backup into a 5.0.x backup by any chance?
