Migration of Gerrit Server Old to New
In this tutorial, we will be migrating our gerrit 2.13 to a new server running gerrit 2.15
Prerequisites
To complete this tutorial, you'll need the following 2 nodes
- Database node
- New gerrit node
Environment
Old gerrit
OS | MYSQL | MYSQL version | Gerrit version | Authentication |
Ubuntu 14.04 | On Localhost | 2.13 | LDAP |
New gerrit
OS | MYSQL | MYSQL version | Gerrit version | Authentication |
Debian 9 (Stretch) | On remonte host | 2.15 | LDAP |
MYSQL node
OS | MYSQL | MYSQL version |
Ubuntu 16.04 | server version |
STEP 1 On old gerrit node
Stop gerrit
Login to your gerrit server with the gerrit user or the user running gerrit. Navigate to /gerrit/bin and run
sudo ./gerrit.sh stop
Backup gerrit database
Login to your old gerrit node and backup your gerrit data base. In this case the database name is reviewdb. I use mysqldump to backup the database to a file.
mysqldum -u gerrit -p database reviewdb > reviewdb_backup.sql
If prompt, enter you mysql password. This will backup your database reviewdb to a file called reviewdb_backup.sql
STEP 2: On the MYSQL server
I am going to convert the installation for a MYSQL server in this tutorial. I assume, you have already MYSQL server running on your node. login to mysql and create the database reviewdb and the user gerrit, grant all privileges to gerrit user.
STEP 3: On new gerrit node
Installation
Make sure that you have Ubuntu 16.04 installed on you new gerrit node.
