Question about Symantec PGP products (SEMS / SEEMS)

Hello All,

I've got a question about Symantec PGP products.
Maybe you can help me with it...

One of our Customers purchased the following licenses:
Symantec endpoint encryption and Symantec PGP File share encryption

Can i manage those with the SEEMS? or should i use the SEMS?

followed that, If i've got an existing (old and unlicensed) SEMS, Can i use it and licensed it or should i install a new SEMS?

Thank you,
Shai
