Upgrade from Hammer LTS to Infernalis or wait for Jewel LTS?

Hi,

I've got two questions!

First. We are currently running Hammer in production. You are thinking of upgrading to Infernalis. Should we upgrade now or wait for the next LTS, Jewel? On ceph releases i can see Hammers EOL is estimated in november 2016 while Infernalis is June 2016.
If i follow the upgrade procedure there should not be any problems, right?

Second. When Jewel LTS will be released, does anybody know if we can upgrade straight from Hammer or first we need to upgrade to Infernalis and then Jewel. If the latter is the case i see no reason not to upgrade now to Infernalis and wait for Jewel release to upgrade again. This way we can take advantage of the new features in Infernalis.

Also what is the correct order of upgrading? Mons first then OSDs?

Any input on the matter would be greatly apreciated.

Thank you.
