For the next two month there will be a nice project:
My zimbra-NE production-installaton needs to be transformed from
1) ubuntu-8.04 --> to ubuntu-10.04
2) 32-bit version --> to 64-bit version
3) base-domain "domain-old.com" --> "domain-new.com"
May be, doing an complete new installation will be the best.
But data-restore in a new base-domain may result in some conflicts, i think.
What is the most handy way for such project?
I think there are many admins thinking about these problems.
Do you plan some installer-scripts for such transforming-projects in future zcs-releases?
