I did something very similar two weeks ago: from TSM 4.1.2 upgrade to
4.2.1 and further to 4.2.1.15.

Two remarks:
 After installing 4.2.1 from CD, the DRM license certificate (drm.lic)
   was missing. I fetched it from an older 4.2.0 installation.
 The fileset tivoli.tsm.devices.aix43.rte is still on level 4.2.1.0.
   A newer level of this fileset is contained in fix 4.2.1.13, but not
   in 4.2.1.15. So, if you want to have it, you will have to upgrade to
   4.2.1.13 in between.

You might also consider upgrading to 4.2.2.0, which I did on a different
server on Tuesday (from 4.1.2 via 4.2.1.0 to 4.2.2.0). Besides the
drm.lic issue, it went smoothly.
