No. I am trying to replicate the file locally ( on to the same data mover and on to the same file system ) .

Do you mean 1-N like replicating the same source file system to multiple destinations ?
Officially its 4
What are you trying to do ?

is this a one time copy or you need to keep these session running at all times ?

My guess would be getting an exam question answered without having to do the legwork ☺

I am looking to keep these sessions running for some testing.
At what level is this limitation set ? Like at the data mover or file system .
Is there any specific reason why the limitation is different for one time copy or keeping rep sessions running is different ? What is the limit ?

Does this mean that I can create more sessions if CPU utilization is low ? Could you also explain about RPQ ?

If this is onto the same data mover on the same system - why not use a writable checkpoint of the fs instead ?

For ongoing replication sessions I dont think that it is a hard limit.
Is is more of question of Memory usage and what we actually tested.
For one-time / Initial copy I think we Limit the number of concurrent session to Limit CPU
If you need more than the supported Limit you should work with your EMC contact to raise an RPQ

RPQ is a process to ask EMC engineering whether a certain configuration can be supported on a case-by-case basis
Your EMC technical contact should know how to do that
