I've done this numerous times and never had to uninstall. Make sure you mksysb & savevg before hand.

If I recall correctly, 8.1.7 is the minimum version required for AIX5.2 for 32 bit and 9.2.0 for 64 bit

I recently did a migration from Aix 4.3 to 5.3 and didn't have to do anything with Oracle (8.1.5). I did find a few things worth knowing about. After the migration install any vmtune changes i made in 4.3 were lost and my ulimits for the oracle user went back to default.
Hope this helps

oracle 8.1.5 has been 'out of service' for some time, but as it is 32bit, it should still work on AIX5.2 as the AIX 32bit runtime environment hasn't changed since AIX4.3.3.
oracle relink all still is a good idea anyway.
I run 8.1.7 databases on AIX5.2 for an SAP system that has been stagnant at SAP4.6/ORA817-32 for some time. Will probably go to 9i-64 in the near future...
Make sure you keep the AIX kernel at 32bit, because you need to install kernel extensions for your oracle software that won't fit in a 64bit AIX kernel.
if you set vmtune attribute of sys0 to pre-5.2 then you can keep on using your /etc/rc.vmtune script or the like, but you will have to modify it
The vmtune sample program has been replaced by vmo and ioo commands. If you have an output of vmtune on 4.3.3 and run vmo -L and ioo -L on 5.2 you'll get the idea which tunable needs to be set. vmo and ioo are a bit picky on which tunable you set first, because there are some dependencies.

Yes,
oracle has created a 64-bit version of the post-wait kernel extension...
Another solution would have been (as mentioned earlier) to revert to AIX 32-bit kernel, then your AIX43 post-wait kernel extension (32bit) version would have loaded and oracle would have started.
there is info on how to change between aix 32bit and 64bit kernel in this forum.
