I am currently on v4.01 IR7. I would like to upgrade to V7. If I do the
upgrade will all the workstations still be able to access the NAL screen
and use the applications with the old v4.01 IR7 agent on or will the
workstations need upgraded immediately to the new V7 agent?

Are there any issues with upgrading any one is aware of?

I am running NW 6.5 SP4a, iPrint, Netstorage, Virtual Office, Groupwise

Thanks for any help.
