Help with Audio Assets properly updating to next engine version?


We are only musicians and we don’t understand a lot in UE. We have previously made an update for one of our audio asset and received feedbacks about errors. Now we need to make an update (music audio asset) from version 4.25 to version 4.26 and we don’t know how to do it correctly so that the creators don’t have any problems.

Please tell me step by step what needs to be done?

P.S. will it be more convenient to buy music in .wav or .mp3 format from our store instead of audio assets for / in the engine?
