Storage Migration Service - Backup and Restore SMS Database

Hi

In the process of migrating from Windows Server 2012 R2 to Windows 2019. SMS is process was working and we've transferred about 20TB of data. A Windows Update was applied and its broken something on the SMS Orchestrator / Proxy.

We now want to have the SMS Orchestrator / Proxy server re-installed, but want to maintain the existing transfer status. In testing; re-installing the Orchestrator / Proxy server erases all progress in a file server migration. I want to avoid starting the migration from scratch again, its a lot of data and files to re-copy.

I've tried in a test environment to copy the database files in  (C:\ProgramData\Windows\StorageMigrationService) from the original SMS implementation to a new SMS implementation, but it seems like it results in a certificate error, does anyone know how to deal with this?
