Upgrading from Asset 7.4 to R2023-5-15 on QNAP

[Gidders]

The installation instructions don't mention anything about upgrading from a previous version so: -

1) Do I need to uninstall 7.4 or do I just install R2023-5-15 over 7.4
2) Either way - will my Folders & Options settings be preserved?
3) If not, what do I need to do to copy across or is it a manual process to reset everything (I hope not)

Thanks

Install over the top and your options should be preserved.
