Is it possible to update from CURRENT to RELEASE ?

[Manish Jain]

Hi,

I am running FreeBSD 12-CURRENT (amd64) for experimental purposes.

I noticed at the time 11-RELEASE was announced that FreeBSD documented 
how to use freebsd-upgrade to update from 10.x to 11.

I wish to find out whether it would be possible, when 12-RELEASE is 
available, to move from CURRENT to RELEASE ?

Thanks for any information.
