Migrating to Sequential Serial Numbers v2 - dogtagpki/pki GitHub Wiki

Overview

Warning
 This feature is still being developed. Do not use in production.

Existing CA instances using SSNv1 can be migrated to SSNv2 using the pki-server ca-id-generator-update command. The command will take the generator type to update and the new generator name, then update the information in CS.cfg and in DS for the new generator.

For requests the command will perform the following operations:

  • Update the dbs.request.id.generator to legacy2.

For certs the command will perform the following operations:

  • Update the dbs.cert.id.generator to legacy2.

  • Update the following parameters to hexadecimal with 0x prefix:

    • dbs.beginSerialNumber

    • dbs.endSerialNumber

    • dbs.nextBeginRequestNumber

    • dbs.nextEndSerialNumber

    • dbs.serialCloneTransferNumber

    • dbs.serialIncrement

    • dbs.serialLowWaterMark

  • If there are no allocated ranges available, update the nextRange to dbs.endSerialNumber + 1 and store it as decimal.

  • If there are allocated ranges find the last range, and if the range belongs to the instance being migrated get the endRange value and update the nextRange to endRange + 1 and store it as decimal.

  • Finally, update the beginRange and endRange in all ranges belonging to the instance being migrated to decimal.

Migration Process

Warning
 The migration process must be done in parallel for all PKI instances. Complete each migration step for all PKI instances before proceeding to the next step.

Step 1: Stop all PKI instances in the system. In the latest PKI version it can be done with the following command:

# pki-server stop --wait
Warning
 At this point it’s highly recommended to back up all PKI and DS instances in case it’s necessary to rollback the migration.

Step 2: Once all PKI instances are stopped, update all PKI instances to have the latest PKI packages that supports SSNv2. For Fedora, it can be done with the following command:

# dnf update dogtag-pki

Step 3: Once all PKI instances have the latest PKI packages, switch to SSNv2 with the following commands:

# pki-server ca-id-generator-update --type legacy2 request
# pki-server ca-id-generator-update --type legacy2 cert

Step 4: Once all PKI instances have switched to SSNv2, restart all PKI instances in the system. In the latest PKI version it can be done with the following command:

# pki-server start --wait
Warning
 Verify that everything is working properly. If there is a problem it might be necessary to restore all PKI and DS instances from the backup.
