Reinitialize Open Invoice File

I have a unique situation where Sage 100 was used 3 years ago and then they moved to another ERP. Now 3 years later they are moving back to Sage 100 and I have upgraded them to Sage 100 2019. I migrated their company that they used 3 years ago because all of their Sage customers, inventory items, vendors, COA are still good and they want be able to look at the Sage history on sales, etc. However,  I need to zero out open AR  & AP invoices. There are hundreds and rather than importing a cash receipt, I tested reinitializing AR Open invoice file and AP Open invoice file. They are ok with losing these invoices but are there any repercussions I'm not considering?
