VM export import Vs fail over

Dears

I have a VM that is quite large (2TB) that I need to
move from a physical server to another temporarly so that I can format the original server and re put back that VM there.

what is the safest way and the least disruptive ?
do I create a replica on the other server and once replication is done then i fail over ? or do I export and import the VM ?
Exporting  and importing will take around 20H which i could eventually find on a Sunday (no need for the VM to be up).
But replica is smoothier... and will not need the VM to stop but for few min..
My only concern is that once the replica is ON and the original server is back online can I again do the same ? replica from the replica to the main server ?

Kindly your experience ....

Thanks
