We are currently running an iseries 800 at V5R2.
We will be installing an IBM 520 V5R4 server.
For a period of time we will be running both systems. Users will access both the 800 and the 520.
My concern is with Client Access. Can the Verison of Iseries Access for windows for the 520 V5R4 be used by the the 800 at V5R2? Must we have two versions of Client Access on each PC that needs to use both systems?
