[Freesurfer] Using FS v5.3 for group analysis with recon-all done with FS v5.0

Dear experts,

I'd like to use Freesurfer v5.3 to make group analysis on quantitative CBF maps computed in volume and projected on fsaverage surface.

Knowing that all my subjects have been recon-all with FS v5.0, is this neccesary to me to relaunch recona-all to all my subjects with FS v5.3 before I do my group analysis ?

Precisely, until now I have only used from FS v5.0 : -> "T1.mgz" to register ASL on anatomical -> "mri_vol2surf" to project CBF maps on fsaverage surface and smooth them

Thank you for replying !

Best,
