You'll need to install 4.2.0.0 from the install CD first, and then apply the
4.2.1.0 PTF, and then the 4.2.1.15 PTF.

I just moved from 3.7.4 to 4.2.1.13 with no (as of yet) problems.

1) Quiesce TSM
2) Do at least one full database backup (upgrades are one-way) (I did two --
I'm paranoid)
3) Shut down TSM
4) Install 4.2.0.0
5) Update to 4.2.1.0
6) Update to 4.2.1.15
7) probably want to reboot here, if you're using TSM device drivers
8) Start TSM and run through your Q/A process

It took me about 5 hours, including the Q/A.
