So I started the data migration for the STG archives - should be done in about 15 hours from now (running for cca six hours already) - estimated on the number of results that were already converted.
If that goes well, I'll start the PROD archives migration tomorrow, and start working on merging the archives with the "base".
If nothing goes sideways, we should have all the data in one place by the end of this week.
