No you have to jump through every version in the upgrade path. Otherwise you will most likely break your install when certain migrations are missed.
So your first upgrade is 11.11.8, then 12.0.12, and so on as per my previous post. Make sure you refer to the upgrade docs and make sure after each upgrade that you check that background migrations have finished before starting the next upgrade. Everything is in the docs. If you follow it, you cannot go wrong.
And make sure you have a backup of your server to restore if something does go wrong. Reading the docs and instructions is important to minimise the amount of problems later.
