SugarCRM 6.5.20 to SuiteCRM 7.1.8

First I tried to upgrade from SugarCRM 6.5.14 with SugarCE Migration 6.5.x to SuiteCRM 7.1.8.zip, but got some error messages. Then I tried to use Sugar 6.5.16, 6.5.18 and 6.5.22 as a basis, but nothing worked.

After that I read this thread https://suitecrm.com/forum/installation-upgrade-help/5569-sugarcrm-6-5-21-to-suitecrm-using-sugarce-migration-6-5-x-to-suitecrm-7-1-7-not-working

telling that “SuiteCRM currently runs off of the SugarCRM 6.5.20 core.”

I updated my SugarCRM 6.5.14 to 6.5.20 and again used the same migration package as mentioned above.

Got error message again: “Database failure. Please refer to sugarcrm.log for details.”

sugar.log tells:

What´s going wrong?
