How do I upgrade from 7.0.2 to 7.1.5 cucm?

[Rodrigo Ruiz Vinchira]

Hello Community; 

I have a question and would like to resolve it here. 

Currently I have a cluster with Version 7.0.2.22900-3 a publisher and 6 suscribers. 

I need to upgrade to Version 7.1.5, I have read the release in relation to this type of upgrade and apparently should not have any problems, check the requirements of equipment and features and I'm inside you need; but I read a little old paper in 2009 reporting that to reach this version I must first pass through an intermediate version, like how to go from 7.0.2 to 7.1.2 and finally 7.1.5 

Could anyone help me with this doubt, or if they can refer me a document where I clarify this, or if someone already had to do this kind of upgrade? 

Thanks for the help.

Hi,

This should be a direct upgrade meaning that you can go directly from 7.0.2 to 7.1.5.  Just have your licensing set aside in case you have any issues and need to reapply them.

This is not a refresh upgrade, all 7.X uses the same RHOS version
