Migration Procedures

Migrate Self-hosted to Cloud

To migrate from a self-hosted server to the Cloud:

1. Create a full backup of the ./bwdata directory of your self-hosted Bitwarden server. In particular, you will need access to ./bwdata/core/attachments to manually upload file attachments to the Cloud (Step 5).

   Tip

   If users are exporting their Personal Vaults over a period of time, you may need to re-sync the items from your ./bwdata/core/attachments directory to your backup location and upload any new items in the event that they change during the cut-over period.

2. In your self-hosted Web Vault, export your personal Vault data or export your Organization Vault data. If you’re migrating an Organization, encourage your end-users to export their Personal Vaults as well.

3. Open the Cloud Web Vault. Most users will have previously created Cloud accounts for billing purposes, so log in to that account. If you were previously a free user without a Cloud account for billing, create an account now.

   Tip

   If you’re migrating an Organization, you’ll already have a Cloud Organization established for billing and licensing purposes. For smoothest transition, we recommend using this already-established Organization rather than creating a new one.

4. Still in the Cloud Web Vault, import data to your Personal Vault or Organization Vault.

   Note

   Importing data to an Organization will automatically re-create your Collections and add the relevant Vault items to them.

5. Manually upload file attachments to your Personal or Organization Vault.

Organizations-only Next Steps

If you’re migrating an Organization to the Cloud, continue with the following steps:

1. (Enterprise Organizations Only) Re-implement your Enterprise Policy specifications and/or configure Login with SSO.
2. Manually re-create user Groups in the Cloud and assign them to the proper Collections.
3. Start inviting users to your Organization manually or using Directory Connector.

Migrate from one host to another

To migrate from one self-hosted Bitwarden server to another:

1. Stop your existing Bitwarden server by running ./bitwarden.sh stop. When you run this command, Bitwarden will go down for anyone currently using it.
2. Make a full copy of the ./bwdata directory of the old server. This copy will be used to recreate your configuration, database, attachments, etc. on the new server.
3. Install and deploy Bitwarden to your new server.
4. Once the new Bitwarden server is set up, replace the newly-created ./bwdata directory with the copy from the old server.
5. Print the new Bitwarden server’s UID by running id -u bitwarden.
6. Open the file ./bwdata/env/uid.env and check that the listed values match what was printed in the previous step. If they do not match, replace both values with the result of id -u bitwarden.
7. If you specified a different server domain during Step 2, edit the following:
   • In ./bwdata/config.yml, change the url: value to the new domain.
   • In ./bwdata/env/global.override.env, change globalSettings__baseServiceUri__vault= to the new domain.
8. Run ./bitwarden.sh rebuild to apply changes to config.yml and global.override.env.
9. Start your Bitwarden server with ./bitwarden.sh start.
