Attachments missing when migrating confluence to another server

Phil Jackson

I am using Server 2012 R2 and am trying to migrate Confluence 5.10.3 to a new server. I have followed the instructions to move confluence home and install folders along with the database, but it does not work. Only sees bits and pieces of info. I then try the xml backup and then import into the same version of confluence on the new server, and when I go to check the spaces, they are missing a lot of attachments in the spaces. I am not sure what else I can try. I have tried doing xml backups with and without attachments and then manually dumping the attachments folder into the new server and doing a rebuild of the index from scratch with no luck.

I have followed the following sites to try and get my data imported and neither of these worked.

Hi Phil

Are you performing a full re-index after the migration?

Thanks

Yeah, tried that, and still no luck.

Are you changing OS or Databases? If you could quickly summarize the steps in detail I can try and help. If not, please create a support ticket.

Nope, same OS and same postgresql database. I have tried numerous steps

I followed the instructions in the confluence support to do an install of the same version of Confluence 5.10.3 and same version database pg admin 1.18.1 and I update all the database and install links to point to the directories to the correct locations, and when I go to check confluence, it shows as if it is still a brand new install, but on the home page it shows that changes have been made from anonymous users.
I tried doing an XML backup (both with attachments and without attachments) from the old confluence to the new confluence then a content re-index and it shows all the spaces, but it is missing a lot of the attachments that users uploaded.
I have also tried although I know this is not the correct way of doing it, doing an xml backup from 5.10.3 to 6.0.1 with no luck as well.

Phil,

I suggest the below steps if it is a Confluence Server - Confluence Server migration and the source system is not very large (you are able to create an XML backup).

Create a new database. Install the same version of Confluence on target system ie. 5.10.3 and connect it to the new database.
Install all the add-ons on the target instance to match the add-ons installed on source.
Create an XML backup from source and restore on target system.
Move the attachments folder from source to target home folder.
Perform full re-index.

Let me know how that goes.

Thanks

Bhushan
