Changing your platform

How to change the platform that runs votre instance GitHub Enterprise Server

Dans cet article

In some cases, you may need to change the platform on which votre instance GitHub Enterprise Server runs, such as moving from VMware to Azure.

Recommendations

You should carefully plan any out migration procedures and consider first testing on a staging environment. For more information, see Configuration d’une instance de préproduction.

Moving platforms using a replica will require the least amount of time for the migration process but will require you to make changes to your live environment in order to setup the replication.

Moving via backup and restore will not require any changes to your live environment, however the migration will take a significant amount of time. The specific amount of time to complete the migration will vary based the performance of your backup host, and the network speeds between your backup host and the new instance. Maintenance mode should also be enabled throughout the process otherwise users may be able to make changes which will not be reflected on your new instance.

Warning

You should not use utilities which convert votre instance GitHub Enterprise Server from one platform to another. Doing so could cause unintended side effects such as system instability.

Move platforms using a HA replica

  1. Set up a new GitHub Enterprise Server instance on your chosen platform. See Configuration d’une instance GitHub Enterprise Server.
  2. Configure your new GitHub Enterprise Server instance as a replica. See Création d’un réplica à haute disponibilité.
  3. Failover to your replica. See Lancement d’un basculement vers votre appliance réplica.

Moving platforms using backup and restore

  1. Setup backups for your existing GitHub Enterprise Server instance. See Configuration des sauvegardes sur votre instance.

  2. Set up a new GitHub Enterprise Server instance on your chosen platform. See Configuration d’une instance GitHub Enterprise Server.

  3. Communicate the upcoming downtime to your users and enable maintenance mode. For more information, see the following articles.

  4. Create a new backup of your existing GitHub Enterprise Server instance.

  5. Restore the backup to your new GitHub Enterprise Server instance. If you are using GitHub Actions, see Sauvegarde et restauration de GitHub Enterprise Server avec GitHub Actions activé

  6. Update the DNS to point to the address of your new GitHub Enterprise Server instance.

  7. Disable maintenance mode and let users know they can continue normal operations.
