i am currently on
Code:
Release 6.0.4_GA_2213.DEBIAN5_64 DEBIAN5_64 FOSS edition.
tried to upgrade to latest version a few days ago. didn't work. so i restored my backup. today i was trying to update to 6.0.5. identical behaviour to the upgrade a few days ago to 6.0.8.

upgrade process:

everything fine until:

i looked into any other logfile mentioned here : Log Files - Zimbra :: Wiki (by the way, this page needs to bee updated or am i not finding the latest real "log files" page

so the only error i was able to find in any logfile is this one

Code:
2010-09-17 23:10:52,881 ERROR [main] [] Versions - DB Version Mismatch: ours="64" from DB="63"
2010-09-17 23:10:52,881 FATAL [main] [] system - Data version mismatch.  Reinitialize or upgrade the backend data store.
but there is no solution for that. i did find some threads mentioning this line of code, but no solution.

what am i doing wrong people?? and why isnt there a sign for my wrongness?? PLEASE HELP
