domain managment

I have a domain which buy fr ISP long time ago.So it is managed /HOST in ISP

If I need to move the domain out to other place, maybe godaddy/networksoloution...

I need fill to in all MX/A record again? and need ask the ISP to host again?

Or Just need input A/MX record will be ok? I checked now the nameserver = MY ISP

I still need fill it?
