Old Save, New Launch sites question

[gmeine921]

Have a sandbox save from IDK which version offhand.  Been playing through the new latest and greatest with no issues and a few smaller mods.  I'd like to give the new launch site(s) a try.  Any ideas on how to modify save file to be able to gain access to them?  Made new Sandbox test save and it has them.  Comparing the 2 sandbox files has the only difference being gameplay items (ships / records / crew) and a different seed.  Can post my save file if anyone wants to take a look.

Go to the pause menu, click "Difficulty Options" at the top. Then go to the "Basic" tab and enable "Allow Other Launchsites" which is at the bottom of the left hand stack of options.

Thank you!  Never explored that menu previously
