Hi Hector, If there's nothing you want to migrate from your 1.8/XP farms that hasn't already been done, then an uninstall/reinstall is probably almost the tidiest option short of a rebuild. Since they're still running 1.8, it'd be an older version of the o.s. as well? A rebuild may be preferable. Anyway, after the uninstall, make sure you delete anything that's Citrix-related (dirs, registry, ica listener settings etc) before attempting an install of PS4. regards, Rick Ulrich Mack Volante Systems ________________________________ From: thin-bounce@xxxxxxxxxxxxx on behalf of Minero, Hector B CIV K55 Sent: Wed 15/03/2006 5:20 To: thin@xxxxxxxxxxxxx Subject: [THIN] Upgrading to PS 4.0 Hi all , I am building a new farm with PS 4.0 and I'd like to move my old servers to the new farm. The old servers currently have MetaFrame 1.8 and MetaFrame XP FR3. Would it be okay to uninstall 1.8 or XP from those servers and install PS 4.0 and join the new farm? Or should I rebuild the servers?
