activating volume group on system after higher level aix installation

Hi,

if I do install aix 5.3 on the rootvg of an aix 4.3.3 system (having rootvg and data1vg),

is it possible to varyonvg the data1vg after the installation ?
(any caution ?)

There is no problem doing this known to me. Should work without problems.
