2 years ago I was tasked with migrating some vm’s off XEN to VMware, these were my notes:
1.) Take SNAPSHOT!!!!
2.) Uninstall Citrix via add/remove programs (dont restart)
3.) Manually run C:\programfilesx86\citrix\xentools uninistaller.exe (dont restart)
4.) Device Manager (uninstall devices w/Citrix driver) (dont reboot) (May have to uninstall twice)
5.) Device mgr (show hidden devices) look for citrix drivers and uninstall if any are shown
6.) Restart machine – take another snapshot (just incase)
7.) open device MGR, double check for XEN drivers (shouldnt be any)
8.) Open the registry editor (regedit) and navigate to:
HKLM\SYSTEM\CurrentControlSet\Services\
Delete all Keys that begin with “XEN*” and repeat it for all “CurrentControlSet” Keys you may have for example
HKLM\SYSTEM\CurrentControlSet1\Services\
HKLM\SYSTEM\CurrentControlSet2\Services\
Now navigate to:
HKLM\SYSTEM\CurrentControlSet\Control\Class\
and delete the “UpperFilters” value found under the contents of the following two Keys:
{4D36E96A-E325-11CE-BFC1-08002BE10318}
{4D36E97D-E325-11CE-BFC1-08002BE10318}
Repeat it for all “CurrentControlSet” Keys you may have for example:
HKLM\SYSTEM\CurrentControlSet1\Control\Class{4D36E96A-E325-11CE-BFC1-08002BE10318}
HKLM\SYSTEM\CurrentControlSet1\Control\Class{4D36E97D-E325-11CE-BFC1-08002BE10318}
HKLM\SYSTEM\CurrentControlSet2\Control\Class{4D36E96A-E325-11CE-BFC1-08002BE10318}
HKLM\SYSTEM\CurrentControlSet2\Control\Class{4D36E97D-E325-11CE-BFC1-08002BE10318}
9.) goto c:\windows\system32 & delete all xen drivers
10.) reboot & make sure no BSOD
11.) run vmware converter
