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 new gerrit node
Installation
Make sure that you have Ubuntu 16.04 installed on you new gerrit node.
