Upgrading #upgrading

 

Here is the situation.?
The MRRC I belong to is a bit antiquated. They run a Digitrax based system with a DCS-100 command station, and JMRI 4.6 with a Sprog II programming interface.
Of course the decoder definitions are not close to what some of the members run(myself included). Digitrax decoders are limited to series 6 for example.?
I would love to upgrade JMRI (have 5.10 and Java 17 at home with my DCS-52).
The questions remain,
(1) What files should I back up prior to the upgrade? I am thinking since we do not run panels or operations from JMRI just the roster needs to be backed up.
(2) Should I install Java first before the upgrade? I did Java 11 when I first downloaded JMRI 5.10 at home, but have since upgraded my Java.
(3) Will command station and Sprog settings be preserved with a JMRI overwrite upgrade?
 

Is the computer 32or 64 bit? What OS is it running?
If you are just using DecoderPro, you can probably jump right up to current but Java will need to be upgraded to at least 11 prior to upgrading JMRI.
See for help upgrading Java, there are limited Java options for 32 bit computers.
What OS are you using? If it's Windows, just select backup when doing the JMRI install. Updates do not touch the user files.

What computer are you running at the club

Windows? If so, which one??

If it IS Windows, then the upgrades are very easy. You just install a new version “over the top” of the old version. All the user files are preserved

BUT PLEASE READ THE RELEASE NOTES for the version you are upgrading TO. From old releases, there may be some intermediate steps you need to take. Do NOT skip them

It is 64 bit windows from what I understand. Will double check that. Since it is not connected to the internet, they don't bother with updates. I will be going there on Thursday to double check everything, but have the ear of the past president to ask as well. Will update as soon as I know more.
 

All they could tell me for sure, without being at the club, is it is windows 10. Ugh.
