@PatelHitesh-9562 We create a avhdx file and merge it, usually during re-sync process, if it is not getting merged, there are two possibilities 1) There is a third party software that is running and triggering a checkpoint, thus avhdx files getting created 2) Could be an issue with the hyper-v host, which is preventing the merge
Eliminate the first option and if issue persists, we need a support case to be created to troubleshoot the second one.
