Has anyone managed to do a V.5.13(AAXA.7) to V.5.13(AAXA.8) upgrade?
For convenience, I will refere to the FW revisions by single digit numbers 5, 7 & 8:
Have previously just updated from rev. 5 to 8 without any issues.
To answer your question, I tried an update from rev. 5 to 7, no problems encountered.
Then a further update from rev. 7 to 8, no problems encountered.
For all operations, logged in to router GUI @ supervisor level, never tried admin level, likely not significant.
As previously reported, I find there is an issue trying to roll back revisions 8 to 5, have to complete in 2 steps 8 to 7 then 7 to 5, only way it will work for me.
Will be interesting to get your opinion on the new rev. 8 GUI, I was glad to leave it behind and scurry back to rev. 5.
