Migration did not link any of my invoices with my estimates. I've been dealing with Tech help for 5 days now and about 16 hours on phone.

Every estimate I have done and every invoice I have ever done going back 12 years are not linked together. They ae all zeroed out. I have current jobs where I have used progressive invoicing that are not linked to the estimates. I can not bill clients to get paid because I do not know how mu of each item has been paid. I have contracts that I have to provide current billing with previous invoices. I have lost all that. I have been with tech support for 5 days, They deleted my COID and opened and new COID and remerged my desk top with online. Still same issue. They have simply ruined my business with this migration upgrade. I don't seem to be the only one dealing with this issue.
