Hi Mohammed,
if you are life environment, you will need to setup another system to
support multi- foundation, then install 8.95 or 8.96 then you can
apply 8.11SP1 (
8.11.1) over Test environment.
if not , install over current system and do your business test, I suggest to
install 8.11 SP1 Update 1 to have latest ESUs.
