I currently have a Mag 2600 running package v7.2r4 and would like to upgrade to the latest package v7.3r2, is it safe to go from v7.2r4 directly to v7.3r1 then v7.3r2?
I am asking because I'm seeing a number of releases after the current package I am running (v7.2r4), which includes v7.2r5, v7.2r6 and v7.2r7. The other reason I am concerned is because v7.3r1/2 is only 278MB, how does it contain all the recent changes and only contain 278MB?
The releases are cumulative meaning that you get the new stuff in version Y that was in version X. I wouldn't go by straight file size to determine this.
The release notes for a revision you want to move to will tell you if an interim upgrade is necessary or not.
