disable and stopping multipathing on Linux

We have a azure migration coming in , in order to migrate from linux to azure system they would like us to stop multipathing on Linux.

So the question is

how can we disable multipathing ?

what effect it would have on the production linux server ?

I saw "multipath -ll" giving output of 6 mpath, should I use "multipath -f mpatha" and so on so forth ??

or should use "multipath -F" ?? to disable all the devices at once ?

Or let me know if there is a proper procedure to achieve this task ??

Is it possible to make a change with out taking downtime ??

Thanks
