H1B Transfer

[Ratchi]

Hi,

I have received my H1B in 2017 with X company and it started from Oct 2017 and in Feb 2018 i had a new opportunity and changed to a new employer Y by filing visa transfer.

Now its been only a month and my old employer wants me back and negotiations went well and now i want to move back to my old employer.

Is it possible to move back ? should my old employer file a transfer again ? How long should i wait before another transfer ?

Thanks
