Hi all: I am planning my upgrade strategy to move from OES 2015 SP1 to OES 2018. One of the things I would like to change in the format of my various linux native partitions from ext3 to ext4 prior to the upgrade. Yes I know ext3 is fine but now that ext4 is the default I am thinking I want to have my servers as stardard as possible.

I have read up on various ways to do this and have tried on a test server in a VM without success. The system fails to boot and I have to boot to repair mode and edit my fstab file. I don't want to do a server removal and fresh install.

Any suggestions? Thanks, Chris.
