BIG-IP Edge Client TMOS 11.5.3 HF2 vs BIG-IP Edge Client TMOS 11.4.1 HF10

Hi all!

I'm migrating a guest with APM module form TMOS 11.4.1 to TMOS 11.5.3 because of the problem with vpn client on Windows 10 and I wonder if it is necessary to download the vpn client for this new version of TMOS or the vpn client users that they had already downloaded works?

Any help would be greatly appreciated.
