Migration not executing from jpa server 6.6.0 to 8.4.0

[Andrea Caloni]

Hello, I am trying to update an instnce of jpa server running on a Microsoft SQL server DB, from 6.6.0 to 8.4.0, using hapi-fhir-cli tool.

When I start it, I can see that table 'FLY_HFJ_MIGRATION' is created, but in the output.log I find a lot of messages like this:

Skipping task xxx because schema is being initialized

At the end of the process:

[HapiMigrator.java:169] DEBUG c.u.f.j.m.HapiMigrator Skipping task 8.4.0.20250729.2 because schema is being initialized
[HapiMigrator.java:187] INFO  c.u.f.j.m.HapiMigrator Skipped 735 migration tasks because schema is being initialized
[HapiMigrator.java:197] INFO  c.u.f.j.m.HapiMigrator Completed executing 4 migration tasks: 4 succeeded, 0 failed.  3 SQL statements were executed.

I would expect much more than 4 migration tasks to be executed from version 6.6.0 to 8.4.0. Is there something I should configure additionally ?

Thanks, Andrea
