Hello @amitabh.jain,

Thank you for contacting us about this. It appears the issue is caused by this line:

caused by: liquibase.exception.LockException: Could not acquire change log lock. Currently locked by f1ab74d41290 (172.17.0.2) since 8/12/19 7:06 PM
at liquibase.lockservice.StandardLockService.waitForLock(StandardLockService.java:230

You can release the lock manually by executing the SQL query below on the Confluence database. 

If that doesn't work, please Raise a Support Ticket with our Migration Team and include a copy of your Support Zip, and we'll be able to help you out.

Best regards,

Shannon

hi,

We have the same problem, running on an H2 database (not able to run queries)

We like to move to the cloud version.

Confluence version 7.4.6
Versienummer 8402

Database naam H2
Database versie 1.4.196 (2017-06-10)
Database-dialect org.hibernate.dialect.H2Dialect
Naam Database Driver org.h2.Driver
Database Driver Versie1.4.196 (2017-06-10)

 

Could you please help me?

Hi Bas,

H2 databases are for evaluation only. You need to migrate your database onto an external database before migrating to Cloud. You can find a list of supported databases from our page on Supported Platforms on Confluence.

For information on connecting to the H2 database and performing the migration, look at Embedded H2 database information. You can find the migration steps at the bottom of this page.

If you have any trouble, please raise a support ticket with our Migration support team!

Thank you,

Shannon
