Migrate from ZITADEL

This guide explains how to migrate from ZITADEL, this includes

• ZITADEL Cloud to self-hosted
• ZITADEL self-hosted to ZITADEL Cloud
• ZITADEL v1 (deprecated) to ZITADEL v2.x

Considerations

The following scripts don't include:

• Global policies
• IAM members
• Global IDPs
• Global second/multi factors
• Machine keys
• Personal Access Tokens
• Application keys
• Passwordless authentication

Which results in that if you want to import, and you have no defined organization-specific custom policies, the experience for your users will not be exactly like in your old instance.

note

Note that the resources will be migrated without the event stream. This means that you will not have the audit trail for the imported objects.

Authorization

You need a PAT from a service user with IAM Owner permissions in both the source and target system.

Source system

1. Go to your default organization
2. Create a service user "import_user" with Access Token Type "Bearer"
3. Create a personal access token
4. Go to the global instance settings
5. Add the import_user as manager with the role "IAM Owner"

Save the PAT to the environment variabel PAT_EXPORT_TOKEN and the source domain as ZITADEL_EXPORT_DOMAIN to run the following scripts.

Target system

1. Go to your default organization
2. Create a service user "export_user" with Access Token Type "Bearer"
3. Create a personal access token
4. Go to the global instance settings
5. Add the export_user as manager with the role "IAM Owner"

Save the PAT to the environment variabel PAT_IMPORT_TOKEN and the source domain as ZITADEL_IMPORT_DOMAIN to run the following scripts.

Clean-up

You should let the PAT expire as soon as possible. Make sure to delete the created users after you are done with the migration.

Use file

Export to file

To export all necessary data you only have to use one request, as an example:

curl  --request POST \
  --url $ZITADEL_EXPORT_DOMAIN/admin/v1/export \
  --header "Authorization: Bearer $PAT_EXPORT_TOKEN" \
  --header 'Content-Type: application/json' \
  --data '{ 
    "org_ids": [ ], 
    "excluded_org_ids": [ ],
    "with_passwords": true,
    "with_otp": true,
    "timeout": "30s",
    "response_output": true
}' -o export.json

Field	Type	Description
org_ids	list of strings	provide a list of organizationIDs to select which organizations should be exported (eg, [ "70669144072186707", "70671105999825752" ]); leave empty to export all
excluded_org_ids	list of strings	to exclude several organization, if for example no organizations are selected
with_passwords	bool	to include the hashed_passwords of the users in the export
with_otp	bool	to include the OTP-code of the users in the export
timeout	duration string	timeout of the call to export the data
response_output	bool	to output the export as response to the call

Import from file

note

To import the exported data into you new instance, you have to have an already existing instance on a ZITADEL, with all desired configuration and global resources.

Then as an example you can use one request for the import:

curl --request POST \
    --url $ZITADEL_IMPORT_DOMAIN/admin/v1/import \
    --header "Authorization: Bearer $PAT_IMPORT_TOKEN" \
    --header 'Content-Type: application/json' \
    --data '{
        "timeout": "10m",
        "data_orgsv1": '"$(cat export.json)"'
}'

Field	Type	Description
timeout	duration string	timeout of the call to import the data
data_orgsv1	string	data which was exported from ZITADEL V1

Use Google Cloud Storage

Export to GCS

note

To use this requests you have to have an access token with enough permissions to export and import. The used serviceaccount has to have at least the role "Storage Object Creator" to create objects on GCS

To export all necessary data you only have to use one request which results in a file in your GCS, as an example:

curl  --request POST \
  --url $ZITADEL_EXPORT_DOMAIN/admin/v1/export \
  --header "Authorization: Bearer $PAT_EXPORT_TOKEN" \
  --header 'Content-Type: application/json' \
  --data '{ 
    "org_ids": [ ], 
    "excluded_org_ids": [ ],
    "with_passwords": true,
    "with_otp": true,
    "timeout": "30s",
    "gcs_output": {
        "path": "export.json",
        "bucket": "caos-zitadel-exports",
        "serviceaccount_json": "XXXX"
    }
}' -o export.json

Field	Type	Description
org_ids	list of strings	provide a list of organizationIDs to select which organizations should be exported (eg, [ "70669144072186707", "70671105999825752" ]); leave empty to export all
excluded_org_ids	list of strings	to exclude several organization, if for example no organizations are selected
with_passwords	bool	to include the hashed_passwords of the users in the export
with_otp	bool	to include the OTP-code of the users in the export
timeout	duration string	timeout of the call to export the data
gcs_output	object(data_orgsv1_gcs)	to write a file into GCS as output to the call

data_orgsv1_gcs object:

Field	Type	Description
path	string	path to the output file on GCS
bucket	string	used bucket for output on GCS
serviceaccount_json	string	base64-encoded serviceaccount.json used to output the file on GCS

Import to GCS

note

To import the exported data into you new instance, you have to have an already existing instance on a ZITADEL, with all desired configuration and global resources. The used serviceaccount has to have at least the role "Storage Object Viewer" to read objects from GCS

Then as an example you can use one request for the import:

curl --request POST \
    --url $ZITADEL_IMPORT_DOMAIN/admin/v1/import \
    --header "Authorization: Bearer $PAT_IMPORT_TOKEN" \
    --header 'Content-Type: application/json' \
    --data '{
        "timeout": "10m",
        "data_orgsv1_gcs": {
          "path": "export.json",
          "bucket": "caos-zitadel-exports",
          "serviceaccount_json": "XXXX"
      }
}'

Field	Type	Description
timeout	duration string	timeout of the call to import the data
data_orgsv1_gcs	object(data_orgsv1_gcs)	to read the export from GCS directly

data_orgsv1_gcs object:

Field	Type	Description
path	string	path to the exported file on GCS
bucket	string	used bucket to read from GCS
serviceaccount_json	string	base64-encoded serviceaccount.json used to read the file from GCS
