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

Server Information
OS MYSQL MYSQL version Gerrit version Authentication
Ubuntu 14.04 On Localhost 2.13 LDAP

New gerrit

Server Information
OS MYSQL MYSQL version Gerrit version Authentication
Debian 9 (Stretch) On remonte host 2.15 LDAP

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.
