Simply Accounting 8.5B database repair before upgrade

I need some contacts for help to repair our Simply Accounting 8.5B database before we proceed to upgrade to the current version of Sage.  I spoke to Sage Support and they indicated they have a "Repair for Conversion" service to repair the company file from version 8.5B and in the process this will also convert it to the most current version of Sage 2022.  Our business is not able to leap to Sage 2022 over the weekend and change our Accounting Workflow without the necessary training.  

Does anyone know of a Canadian company that is able to just repair our 8.5B database first so we can slowly transition to Sage 2022?
