Currently there is no parity between F&O and CE when it comes to merging accounts. If a user mistakenly creates a duplicate account in either app and the merge function takes place the two apps behave differently. CE will move orders into one account and under F&O they will stay under the same account. Because of the disparity you are unable to merge accounts when using dual-write without resorting to an external resource.

I would like the apps to have the same functionality so that there are no issues presented when merging two accounts in a dual-write instance.
