Hi everyone,

Thanks for all your opinions.

I've used the tool with '--force' parameter and it upgraded just fine. Now I'm having some side effects like:
"grep: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory"

Also, OpenVAS does not boot yet.

I'll try a clean install and forget all application-related history.

yeah, I cant agree more.

The only time the migration process worked for me was on a freshly
installed centos6 box, with a minimal install and then upgraded
immediately. Admittedly, the only time I ran this was about 6 to 8
months back.

When third party repos get involved, all bets are all. Similarly when
desktop components and lots of user data is involved, many bets are also
