Hello all, Due to PCS 8.1 going EOS at the end of this year (2018) I need to prepare an uprade of our MAG4610 cluster. Following advice in KB40072 I plan to go for latest maintenance release of the most recent software branch - that is 8.3R4.0.    In 8.3R4.0 Release Notes I read that upgrade from any version of 8.1 is "Compatibile" but path from latest maintenance version of 8.1 (8.1R13) is "Qualified" - I am not 100% sure what does that mean and would be gratefull if anyone could rectify what is the difference?   Is it safe to go directly from 8.1R6 to  8.3R4 or support recommendation is to take intermediate step through 8.1R13? Please also share your experience whith  8.3R4 and similar upgarde paths. Are there any unusual checks recommended to perform in my case?   Thanks Adam ... View more
