TSM 6.3 (CentoOS 5.9) -> TSM 7.1

Hello everybody,
this is my first post :)

I have a working TSM 6.3.3 installed on CentOS5.9. I've been asked to upgrade this to TSM 7.1. Now I notice that TSM 7.1 only supports CentOS/RHLE 6.

I guess the approach should be a migration + upgrade.

What steps would you suggest?

Or is it possible to make TSM 7.1 work on CentOS/RHLE5 ?

Thanks in advance,
Luigi
