The method I described allows to update from any version to any newer version, anytime, and continually.

So, if you are happy right now with the features, performance and security of 2.1.13, you can upgrade to that one and continue using it until your circumstances change. And then you can upgrade to a newer one.

Hello Badlop,

thanks for your fast suggestion and excuse me for my delayed response!

I take this opportunity to also do another question:
how can I migrate to the new/last stable version from my 2.1.13 (that is defined as "obsolete")?
Or in this moment can I upgrade to the 2.1.13 (even if it's defined obsolete) and waiting for new version (maybe 3.0)?
Thanks in advance.

"inster old nodes in the cluster of new nodes": this seems a bad idea, because ejabberd updates the tables content when it starts. So, you'd end up mixing content of tables with different formats.

Better idea:
1. Setup a new ejabberd node using 2.1.13
2. Copy mnesia spool dir of one old 2.1.8 node to the machine where 2.1.13 is installed.
3. When you start ejabberd 2.1.13 in the new node, it will update the tables content.
4. Check it works correctly
5. Setup a second 2.1.13 node
6. Insert the second node in the cluster
