HELP! Update is hanging since over 28 hours.

Hello,

Yesterday morning I started to upgrade from Version 7 to Version 8. I did everything exactly like in your documentation. But now the MySQL5 Database is hanging since one day. It just says:

417 out of 676 tables are restored in MySQL5 Database and doesn't move on. Please help me, because I don't want to abort the installation and lose everything.

Okay recent update, now it moved on to 418 out of 676 after 2 over hours. But our company depends on the alerts and information from OpManagerl, so it's impossible to wait maybe one week, till it might finish.

Please help me, or give me some advise.

Thanks.
