Syno themselves seem to prefer if you 1st update to 7.0.1.42218.
Their download page lets you specifically pick the correct packages for your model and from what version you’re upgrading.
All that being said… not sure if it’s already safe to update to 7.1. According to their homepage, 7.1 is the latest model and seems to only recently have left beta. No word of DSM 7.2 (maybe I’m looking in the wrong places though).
To whatever version you update, make sure to follow chuckPa’s upgrade guide to the letter to avoid the common caveats.
