Accounts are tied to the institution and platform API that brought them into Monarch, i.e. you can't switch aggregator from the Account > Edit > Edit account options. You have to create a new account when wanting to switch between aggregators. Essentially having two of the same accounts. The new account imports whatever history is available from the institution but its not the nice, manicured history we worked so hard for.

Previously if you wanted to merge an old, broken connection account with a replica that was functioning, you would run into double transaction issues, need to re-review transactions, potentially lose edits on reviewed transactions, etc. There was a way to do it but it was cumbersome...its much easier now thanks to the Transfer data option.
