Migrate SRM DB from SQL to Embedded

Hello

Is it possible or supported to migrate from a SQL Server DB (2012) to the embedded DB and keep data? I found posts about going from embedded to SQL but we want to do the opposite.

Currently running SRM 6.1.2.2

We are planning a migration to SRM 8.1.1 so I understand a workaround might be to do this and then to export config re-install with embeeded and import config but I wondered if there are alternative supported or unsupported options available on our current version.

Thank you
