Ok, having search through the forums on this issue, please refrain from telling to RTFM particularly as regards upgrading from 6.x. I should have been more attentive when looking at the upgrade instructions. My fault.
That having been said, after upgrading if I run zmdbintegrityreport, I get a host of errors telling to me to repair each individual table. As I understand from other posts, this is not a zimbra issue, but a mysql issue. Nonetheless, could someone provide some step-by-step instructions on what I need to do to get all those tables "repaired." I should note that zimbra otherwise seems to be working fine. But I don't want this to be an issue later on.
Thanks for any helpful input anyone can provide!
