Advice on upgrading from version 2.2

[paul.orsillo]

Can anyone offer advice on how to go about upgrading from version 2.2.0 of Enterprise Server to version 4.5. 

This doc: http://developer.couchbase.com/documentation/server/current/install/upgrade-matrix.html#topic_dwm_qfv_xs indicates that there is direct upgrade from 2.5.x but nothing earlier. 

Thank you

Hey Paul, hope you're well. 

The docs indicate what the "supported" upgrade paths are...indicating those that our engineering and QA teams have tested extensively in various scenarios, across multiple OSes, etc.  

I can't say for sure whether 2.2.0 directly to 4.x will definitely work, but I don't believe there are any specific restrictions in the product to disallow it. 

Your "best practice" path would be to upgrade to the latest 2.5.x and then from there to 4.x. 

One thing to keep in mind about going from 2.x to 4.x is a change in how our client libraries bootstrap off the cluster. I'd actually recommend upgrading to the latest version of the SDK if you haven't already as it will be backwards compatible with the older server version and likely give you a smoother upgrade experience. 

Do you have an EE license with us?  If so, I'd recommend getting in touch with support so they can help you through the process. If not, we'll do our best here :-) Regardless, I'd recommend testing out whatever path you choose in your own environment with your own data/applications. 

Hope that helps, let us know what else we can do or if you run into any trouble.

Thanks Perry. 

I hadn’t thought of the 2.5 interim. Great idea. That should make it a lot easier.

The SDK is similarly outdated so that will be coming along immediately after the update - at least that is current thinking.

Happy to help Paul.

I would suggest doing the SDK first if possible, it will give you the smoothest experience when upgrading the server.  

Do you know offhand which version of the SDK (and which language) you're using?

The SDK is .NET in this instance - probably more or less concurrent with the installed 2.2 Server.

There have been a number of improvements since then, I would definitely take a look at upgrading that first to see what the level of effort for you would be.
