Ian,

?

Java 17 from Azul or something like that. At least JMRI 5.10 to start. But do you have any files from the old system? If not, it doesn’t matter. But if you have files like panels etc. then you would need to know what version you had been running. Depending on how old those might have been and it may impact not going with the latest JMRI.
