Migrate OrientDB to H2 stuck on "userToken"

I found in the config database the following entry:

orientdb {db=config}> select usertoken from upgrade_model_versions;

+----+---------+
| #   |usertoken|
+----+---------+
|0   |1.1      |
+----+---------+

1 item(s) found. Query executed ` `in` `0.003 sec(s).

I have now updated the value to “1.5”:

orientdb {db=config}> UPDATE upgrade_model_versions SET usertoken = 1.5

Updated record(s) ` `'1'` `in` `0.019000 sec(s).

Then I was able to run the migrator successfully.
I am currently testing, if the migrated Nexus instance is accepting the new H2 database.
