Downsampling entire session?

[Overmann]

I have a bit of an unusual question: Is it possible to downsample an entire session in one go? 
I have a bunch of old session that were recording in everything from 44.1kHz to 192kHz, and I would like to have them all in 44.1kHz. Can mixbus do this? Or are there other programs that can do this that you guys know of?

All suggestions are greatly appreciated

I would recommend to mix the session in whatever samplerate you recorded and downsample one at the last stage (probably after mastering or at final mixdown) for best results.
