I was partially successful using rs.exe and ssrs_migration.rss: https://github.com/Microsoft/sql-server-samples/tree/master/samples/features/reporting-services/ssrs-migration-rss
But, the main problem is that the data driven subscriptions (or even a regular subscription) DID NOT get migrated along with the RDLs. Also, the data source links were blank.
One wrinkle, maybe, is that my source is not on a domain (it is a standalone workgroup).
So my main question is: has anybody successfully used ssrs_migration.rss to migrate data-driven subscriptions along with the RDLs? If so, any advice to someone who constantly gets: "migrating subscriptions for report ... 0 items found"
Thanks.
