Migrate Partial Data from 3.4.1 to 4.3?
Asked by Justin Howe:

Hello,

My organization has Confluence 3.4.1 already loaded with years of data in many different data spaces. We also have 4.3 recently set up on another server that we'd like to slowly migrate data to, first for specific spaces (not all at once) and eventually have everything migrated over.

1) Is it possible to migrate specific data spaces from 3.4.1 to 4.3?

2) If not, is it possible to migrate the entire data set from 3.4.1 to 4.3?

Thanks in advance!

Just wanted to let you and anyone else stumbling on this post that there is no way to ship data directly from 3.4.1 to 4.3.

In order to use Space XML export/import you will need to upgrade your legacy system up to 4.3. Your upgrade path is going to be 3.4.1 - \> 3.5.17 -\> 4.3 to ensure that you pick up the new user management piece in 3.5.x.

From there you can follow the documents linked above to do the space import and export to get your legacy data into your new instance.

I noticed the same information you provided in the documentation that Ramiro linked to, and am awaiting a response from the person in charge of that data space within our organization. We currently have 3.4.1 and 4.3 installed simultaneously on different resources, and I believe they would like to keep 3.4.1 as an in-tact resource for a while until 4.3 is brought up to speed as to mitigate any possible complications. I'm not sure how the licensing goes, but is it possible to duplicate our 3.4.1 installation, upgrade that as per your suggestion, and then once completed scrap our existing 4.3 install? I'm not sure if that's something that can be done with however licencing is registered, etc.

That is not a problem at all. Setting up a test envinronment and performing the upgrade in test is a great idea. You will be able to export your spaces unfettered.

What 4.3 instance do you want to scrap? The instance you are upgrading to 4.3 right?

We have a current 4.3 install that is for the most party void of any data, so that is what we would scrap once the conversion up to 4.3 is done on a duplicate of our 3.4.1.
