Well, since that post I was able to find a way to get Tiger running on the "backup" installation, and I have been able to move ZCS from one machine to the other. The instructions on the blog didn't quite work for me; ultimately I found that I needed to do part 4 step 5 by running ./install-mac.sh -d and pointing it to the .dmg file, as root, from /opt/zimbra/libexec/installer.
However I am still a bit concerned about the apparent non-ability to migrate from Tiger to Leopard. If anyone can confirm that they've done this under 5.0.10, or reproduce the problem, that would be great. |
