hmmm except you have really loads of memory on your box, and therefor a large virtual memory area (what I don't really believe), a 36 GB disk should be more than sufficient for rootvg - except you have a lot of application data in the same vg.
If that is the case, I would suggest you rather create a new VG with bigger pp size on the new disk and a few new filesystems and than just copy/paste the data to these new filesystems. Since you're able to change afterwards even mountpoints, you can keep the filesystem structure you already have.
Keeping a system clean might be the better solution than what you're going to do.
You can than drop the no longer needed filesystems from rootvg and can use the space to extend filesystems, if required.
Kind regards

QUOTAON(8)						    BSD System Manager's Manual 						QUOTAON(8)

NAME
quotaon, quotaoff -- turn filesystem quotas on and off SYNOPSIS
quotaon [-g] [-u] [-v] filesystem ... quotaon [-g] [-u] [-v] -a quotaoff [-g] [-u] [-v] filesystem ... quotaoff [-g] [-u] [-v] -a DESCRIPTION
quotaon announces to the system that disk quotas should be enabled on one or more filesystems. quotaoff announces to the system that the specified filesystems should have any disk quotas turned off. The filesystems specified must have entries in /etc/fstab and be mounted. quotaon expects each filesystem to have quota files named quota.user and quota.group which are located at the root of the associated file system. These defaults may be overridden in /etc/fstab. By default both user and group quotas are enabled. Available options: -a If the -a flag is supplied in place of any filesystem names, quotaon/quotaoff will enable/disable all the filesystems indicated in /etc/fstab to be read-write with disk quotas. By default only the types of quotas listed in /etc/fstab are enabled. -g Only group quotas listed in /etc/fstab should be enabled/disabled. -u Only user quotas listed in /etc/fstab should be enabled/disabled. -v Causes quotaon and quotaoff to print a message for each filesystem where quotas are turned on or off. Specifying both -g and -u is equivalent to the default. FILES
quota.user at the filesystem root with user quotas quota.group at the filesystem root with group quotas /etc/fstab filesystem table SEE ALSO
quota(1), libquota(3), fstab(5), edquota(8), quotacheck(8), repquota(8) HISTORY
The quotaon command appeared in 4.2BSD. BSD
