teTeX --> TeX live: When to migrate?

[Johannes Wiedersich <johannes@physik.blm.tu-muenchen.de>]

I know, sooner or later I will have to migrate from my present teTeX to 
TeX live (currently running etch). Both are available for etch. I'm a 
happy user of teTeX, not missing any features and just wondering of when 
 is the best time to migrate: now, later or should I wait for an 
automatic upgrade in the process of upgrading to lenny, lenny+1, 
whenever it will happen.

Are there any issues to be aware of or is it just an 'aptitude install 
texlive'?

I am developing and using my own .sty files along those of teTeX, and of 
course, I'd rather not break one of those ;-)

Thanks for sharing your experiences!
