I will answer my own question.
We had ran the script again, it had picked up 17 documents that it may have missed ?
All things are connected and running in parallel.
Thank you for your time, and assistance on this.
Sounds like the script didn't capture or restore the mongo files for opc. Are you using the python or Powershell scripts?
We were using the Powershell script for this migration.
Ok, thank you for the info. I ran that script and it appears to be capturing the OPC mongo data (this is where sessions are store) normally. Just to double check, you were successful in the migration when you ran the script a second time?
No problem! Yes, the migration was successful. It acted like it didn't grab our OPC connections at first for some reason.
