First of all I want to thank all the Zimbraphiles and staff out there for being so helpful in the past.
During my last mail panic, Mike Morse suggested upgrading my version from 4.5.3 to 4.5.11 and pointed me toward some documents halfway down this thread.
We have been having more problems with this old version, namely extreme slowness with POP and SMTP, and web interface. After Zimbra services are restarted, things return to normal, but invariably clog up again. I can find nothing telling in the logs except amavisd and clamav complaining. I figure its time for the upgrade.
The documents seem pretty complete, except they assume that the install is fresh. Can anyone point me toward some threads/documents that help with an upgrade of an existing Zimbra... hopefully OSS 4.5.3 to 4.5.11?
Or, if not, what tweaks are necessary to the instructions provided to make them apply to an upgrade?
Thanks in advance-
