Big-IP 10.x can be upgraded to any version of 11.x given your hardware supports the new version. Big-IP 11.x can be upgraded to any version of 12.x given your hardware supports the new version. You cannot upgrade directly from 10.x to 12.x. For more information, refer to:
The Latest Maintenance Release of each Long Term Stability Release are the best choices for security and sustainability. For more information, refer to K5903: BIG-IP software support policy. The lowest-numbered version in the Latest Maintenance Release column is generally considered the most stable while the highest number contains the newest features and security fixes.

If a Big-IP fails to upgrade and further troubleshooting cannot be performed due to time constraints, follow the below steps before reverting to the previous Big-IP version.
Note: The above back out procedure does not apply if you have reset the Big-IP to default settings.
That's correct. I left it worded that way due to the caveat you mentioned and for best practice understanding.
I would recommend going to version 10.2.4 before upgrading into v11/v12 particularly if you have a 6900/8900/11050 as there is an issue with swap file creation if skipped. Can check this via "cat /proc/swaps".
And remember that we have now our brand new 220.127.116.11 TMOS version, which is a Long Term release with 5 years of technical support.
