Anyone tried this yet? I understand you should be able to install over the top, but is there any issue going from FTP to MFT?
I don't think there should be any issues. There can be issues upgrading from a VERY old version (like version 1). 14 should be fine.
Any chance you have a copy of version 14 File Server only?
We're running an older version (12) and are licensed for 14.
I raised a support case late last year as part of a migration process and was told they didnt have a copy of ver 14 for me?
Version 14.0.2 and 14.0.1 are available in the Solarwinds Customer Portal under Downloads > Download a Product
I havent heard of any issues but make sure you go to 15.2.1 not 15.2.0 as you will need to change all user passwords if you use 15.2.0.
I would still raise a ticket with support before you upgrade from 14, just to check there is no specific upgrade path. You could also try it on a test server with a trial before you do it on your production server.
