Just add the -p option to the command. So command
# vmo -p -o minfree=480 -o maxfree=512 -o minperm%=10 -o maxperm%=30
will both set the vmm options and make them permanent at the same time.

However, chances are that the old values from the old AIX and the old haredware are inapropriate for your new system. Because:

minfree/maxfree changed from a per system setting to a per cpu setting and probably is way too low anyway.
maxperm% must go with maxclient%
lru_file repage is available with current 5.3 TL and depending on your application your minperm%/maxperm% values might be not optimal
maxpageahead may be wrong if you changed from jfs to jfs2. In this case j2_maxPageReadAhead=32 is what you want.

to name just four things that come to mind without digging too much into the details.
