Run the Integration Server or Microservices Runtime Migration Utility
If the old installation had multiple server instances, run the migration utility once for each instance to migrate.
If you are migrating Integration Server, you can migrate an old instance to the new instance created during installation, to a new instance you created after installation, or to a new instance the utility creates for you.
If you are migrating Microservices Runtime, migrate each instance to a separate Microservices Runtime installation. Starting in 10.4, each Microservices Runtime supports only one server instance.
If you are upgrading an Integration Server or Microservices Runtime that hosts Deployer, follow the instructions in Upgrade the Asset Build Environment or Deployer.
If you run the migration utility with prompting, and the utility fails to migrate an item, the utility asks whether to continue with the next item or abort the migration. If you choose to abort, the utility exits. The utility does not revert the new product installation. You can address the issue and rerun the utility.
