Unable to migrate data from 3.3.6 to newest 4.1.5

(Sumbrada) #1

I’ve installed a new server for Octopus 4.1.5, on server 2016. I installed SQL 2014 Express on this new server. I have exported data from the 3.3.6 server to a folder and tried to import it on the new server, but receive:

I have also tried simply backing up the existing database and restoring it to the new SQL server, but this fails as well, stating that the master key is invalid. Any ideas?

Hi,

Thanks for getting in touch! Our SQL data structure has changed a lot between 3.3.6 and 4.1.5. Migrating data between these version will not succeed due to this. In order to migrate the data, you have a couple of options. The first option is to upgrade the 3.3.6 instance to 4.1.5, then you should be able to migrate the data with ease.

The other option is to uninstall 4.1.5 on your new server and install 3.3.6, you can then perform your migration, followed by the upgrade on the new server.

It is always recommended that you have a backup of the database and master key before you upgrade. We also have some documentation on the subject which may give you some further bits of helpful information here.

Let me know if you have any questions or run into any further issues here. :slight_smile:

Best regards,
Daniel

Ah, that explains it. I was wondering if it was a data structure limitation between versions. I’m loathe the upgrade our PROD system in place, so I’ll try the side-load attempt where I install 3.3.6 and upgrade that.

Worked like a charm- thanks for the prompt response.
