Welcome to the forums.
When upgrading the first stop is to the JTAC recommended versions by platform kb. This is regularly updated and is the best starting point for choosing a version.
Next you go to the software downloads area in Support.
Support--By Task--Download Software--Junos All versions
Pick your platform here
Choose the version on the right
Now download the release notes for the recommended version.
Here the release notes are organized by platform. The J-series is the same as Branch SRX.
Naturally you read the whole thing, but I concentrate on:
Review known issues and outstanding issues to see if any are going to cause a major issue in your configuration.
Review resolved issues and see what applies in your configuration
This also allows you to prioritze a test plan for after the upgrade.
In your case you may also need a Flash upgrade to 1 gig
And then there is the actual upgrade process which can run in either the web ui or the cli.

Software versions get removed from the public site as they go EOL.
But they are still available via JTAC for issues like this. You can open a ticket and get the specific release listed.
Also, these lists are essentially the fully tested versions for upgrades. Frequently other versions will work, they just are not the supported version. In other words, if it does not work when you open a ticket JTAC will have you go to the supported version first and then upgrade rather than troubleshoot your current version.
So you could just give it a go first.
