I have a number of F14 partitions which must be mounted unchanged on the new F16

I use the same user name on both systems but on F14 I got userID 500 whereas on F16
it became 1000. I wasn't aware of that but learned it the hard way. When I chowned
the permissions to 1000:1000 it worked on F16 but now not on F14.
What is the proper way to fix this problem? I am tempted to reinstall F16 and force
my userID to 500, but the system warns me not to create userIDs< 1000. It is not
feasible to clone the partitions due to space constrains so I am not able to have
identical partitions with different permissions.
The "proper" way to fix this is to do it on the F14 system.
Change your password entry to have uid:gid of 1000:1000. Make the change to the
group file to change it to 1000 as well.
Then, go to all the top of all partitions/directories owned by 500 and chown -R
1000:1000. In other words, make all the changes on the F14 side.
I had to go through this process when I installed F16 since my RHELv4 system had me
as 500:500 and I NFS mount my directories from there. Just took 5 or so minutes.
Reinstalls are never needed to change a user's gid/uid.
I thought of this at the very beginning but I never found out how to change
userID from 500 to 1000. Please explain how to do that.
Thanks
