Upgrade from Marshmallow?

[Android Central Question]

My Galaxy S9 was stolen on vacation, so I had to go back to my S5. The S5 currently has Marshmallow installed. Is it possible to update it to Oreo or Pie?

This will probably have the most resources for this - https://forum.xda-developers.com/galaxy-s5
You could also look into LineageOS...

There is nothing official for that device though.
