[SOLVED] Upgrade 4.5.7 > 5.0 GA Failed

[mikes2277]

After much searching and hair pulling out as 50K email accounts on my server quit working it seems that the Perl RPM in CentOS *Plus* is broken (missing XS that Zimbra needs during install) but the Perl that comes with CentOS (non-Plus) has XS in it. See the below link on how to restore back to the plain Perl with XS support. After I did this my upgrade went perfectly. Everything else in the above posts did not work for me.

This worked for me:

Downgraded perl and mod_perl per the previous post.

Then ran the upgrade for 5.0 GA and it was successful this time!

Thanks for all those who posted suggestons!
