Problem with Extract .Mig files which was taken backup when rest system

Extract .Mig files which was taken backup when rest system when it was not On totally.

In booting option when go reset option dell only recommends to take backup for later restore. But later with new OS not able to restore. Really disappointed

But failed to restore due to lack Dell supporting tool/ no tools availability. USMT tool is no use in case in case your old windows version is 11 and backup taken also taken in win11. But USMT tool only support windows 10.

Really disappointed with Dell laptop.

@Dell Please look into this issue majorly and recommend solution for affected people. Thanks
