Have just upgraded from 6.0.10 NE to ZCS7 NE on Ubuntu 8.04 64 Bit (40 users 95% on GUI)
First time round there was some moaning from the upgrade script about invalid license (obtained via the support portal). This was resolved after the upgrade by re-activating the license from the Admin GUI.
A couple of ZCS GUI issues
1) Print Font Size: My COS Value for Default font size is 10. The new "Print Font Size" attribute was set to 12pt in the default cos and for all users.
zmprov modifyCos default zimbraPrefDefaultPrintFontSize 10pt
However, this appeared to have no effect on the users, so I had to change each one with a little script based on:
zmprov modifyAccount
chris@mydomain.com zimbraPrefDefaultPrintFontSize 10pt
2) The new (excellent) feature to be able to add the signature before or after existing text when replying or forwarding does not get set by the upgrade and the setting must be "applied" by going into preferences and saving (bug ?)
3) I had to disable the "Social" Zimlets in a big hurry on a SME Email server !
I don't think the upgrade should turn them on by default ??
I will post more as I find it.
