From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of alan tropper Subject: [THIN] Citrix Presentation 4.5 Rollup3 hotfix Hi, I am currently looking at installing the hotfix rollup pack for PS 4.5.1, as no hotfixes have been applied to the farm yet being that it is fairly new.. However it looks as though I may also need to upgrade: Web interface from 4.5 to 4.6 Upgrade the Citrix License Server currently 4.5 to 11.5 Then install the rollup patch to all citrix servers (starting with metric servers) Can anyone advise if the above is correct and if there are any issues I should be aware of before upgrading other then the obvious of backups and snapshots? No need to upgrade the WI but it doesn't hurt to do so Upgrade the License Server to 11.5 Install the Microsoft C++ Redistributable Package to ALL XenApp servers Install HRP03: Data Collectors Database connection server Pri farm metric server BU farm metric server Member servers Webster
