Database Migration Wizard Tests Fail Connecting To Postgres

[Jeremy Flint]

I am in the process of migrating our Bitbucket Server (v4.14.0)

from Windows to Linux. My plan is to spin up a Postgres DB on the linux box and migrate the database to that, then move the home folder content.

When I try to test the db migration wizard, I get the following errors:

The configuration entered is not valid. A database connection could not be established. Please check your configuration and try again.

Hi Jeremy,

Check that Postgres is running and that it is listening/accepting connections on port 5432.

So on server 192.168.123.35, check port 5432 is open. And the server you're connecting from can reach this server.

Thanks! Ok, I got the database migrated. I am working on migrating Bitbucket to a new server. So I have:

• Migrated the database.
• Stopped the service on the current server (Windows)
• Migrated the home directory to the new server
• Installed BitBucket on the new server (Linux)
• Ran installer as an upgrade to existing.

When I try to put in the info for the new DB, it tells me there is already data there (duh). How can I get it to use the data already in the DB? Or do I need to install to a clean DB then switch it to use the migrated DB post installation?

An option is to download the tar or zip option, edit the necessary files to point Bitbucket to the current database and home directory then startup. After this, then run the upgrade option.
