Uninstall Avast 4 clients before pushing from ABP console?

We just brought up a new Avast BP server which is currently running alongside our Avast 4 ADNM server.

Do we need to uninstall all of our Avast 4 clients before pushing out from the BP server? Or will the BP server upgrade the clients if it sees Avast already on the machine?

After doing some testing, I answered my own question.

Pushing to a machine with the old Avast client installed seems to work just fine. No uninstall beforehand necessary.

Great work guys. Thanks for making it easier on us!

yes the sbc clients uninstalls the old client before installing itself.

i installed the 4.8 client in a not-standard directory when deployed maybe thats why i found this below out:
keep note that this way the old directories are not deleted
so in the program files directory there will be 2 directories one for the new client and one for the old

in the start menu of windows both the client parent menu option are available

i delete all that manually so far, but ill be making a GPO for it soon when i get more time
