I am currently running old version of Serv-U MFT 15.1.6 on RHEL 6.6 as a virtual host.. Looking for the best path to get to updated RHEL OS 7.9 and Serv-U 15.3.0
Options I have I guess are:
1) clone existing VM host, do inplace upgrade of RHEL and then upgrade Serv-U. I have been told and seen that inplace of a Linux box not the best approach since lots of caveats.
2) fresh VM with target RHEL OS. install old version of Serv-U, install backed up data from old Serv-u host to new one then inplace upgrade Serv-U. This may be interesting in making sure all the SSH keys and certs used are are captured and in place... Also seems the install location are different for Serv-U versions.
3) clone a prod box which has target OS version and a newer (not target) version of Serv-U. tweak hostname, interfaces and such. Not sure though I taking the old server Serv-U backup files and moving them to clone would work or cause issues.
Anybody has insight on how to approach an upgrade of this type: requires Linux OS and Serv-u version to be upgraded.
