Please excuse this question, but if I am currently running 4.5.10 and wish to move everything to 5.0 (on the same server), is this a migration or an upgrade?
That is, if it is an upgrade, all we do is run the usual install script for 5.0 and it will automatically upgrade our 4.5.10 programs AND data to 5.0 format?
Or, do I have to run a 5.0 upgrade, then manually convert/migrate the data from 4.5.10 to 5.0 format?
Just not clear to me. I've been looking to see the experience of others in doing this, but haven't found anything other than this: http://www.zimbra.com/forums/migrati...4-5-5-rc2.html
