## Upgrade from Master Branch (after 0.3.0M6) to 0.3.0M7
Due to changes in the DB migration scripts within PR [#1017](https://github.com/eclipse/hawkbit/pull/1017) the Hawkbit will not start up if one of the following cases is true:
- DB2 database is used
- MSSQL database is used and the sp_action table is not empty
- PostgreSql database is used and the sp_action table is not empty
The script was fixed with PR [#1061](https://github.com/eclipse/hawkbit/pull/1061).
In case you upgrade from 0.3.0M6 to 0.3.0M7 there is no issue. But if you have built the Hawkbit from the master branch between PR [#1017](https://github.com/eclipse/hawkbit/pull/1017) and PR [#1061](https://github.com/eclipse/hawkbit/pull/1061), use PostgreSQL or MSSQL and upgrade to 0.3.0M7, it will fail at startup with the message: `Validate failed: Migration checksum mismatch for migration version 1.12.16`
This can be fixed by adapting the schema_version table of the database. The checksum field of the entry with the version 1.12.16 has to be changed (mind the minus):
- -1684307461 for MSSQL
- -596342656 for PostgreSql
Example for MSSQL: `UPDATE schema_version SET checksum=-1684307461 WHERE version='1.12.16'`
