Upgrading Citrix License Server from 9.1 to 11.x

Hopefully an easy query.

Can I upgrade Citrix Licensing Server 9.1.x to the latest version 11.4.x, or will this cause any issues for XenApp 6.5
I was unable to locate info regarding this on Citrix Forums,

Make a copy of the myfiles folder where the license files are kept. Try an in-place upgrade of the license server.

Worse case scenario if you install the new license server and it doesn't work with your old license file. If that happens, just go to citrix.com, login, go to the license section, return and reallocate your licenses and then download a new license file using your license server's hostname.

The entire process will take just a few minutes. My XenApp 6.5 farm is working with 11.14.0.1 license server I upgraded from the 7.17 XenApp ISO.

Cheers. I'll make sure client provides access to mycitrix first so I can allocate licenses if required.
I was thinking of doing so but am checking just in case. Will update if that went through fine. Thanks.
