Changing work location on old H1B

[Vgn89]

Hi, 

I am currently employed in a company located in state A on H1B status. I am planning to join a new employer located in state B and I already have a new approved H1B filed by them. 

My joining date with the new employer is in 2 months and I intend to continue with the current employer until then.

Can I relocate to state B in the mean time and continue working for the current employer from there? 

If yes, how many days before my last day at the current company can I move out of state A?

If not, will it be okay if I still move out of state A and just maintain my residency (keep an apartment with an active lease) in state A till the last date with my current employer?

Will there be any other H1B status issues that may arise from moving out of state A earlier since my current H1B is tied to this location?

Thanks in advance!
