To Migrate to Anypoint Platform Private Cloud Edition, Version 1.5.2

During the migration process, there may be some downtime as each node is migrated. Any users who are currently signed on are logged off. User may need to refresh the login page before entering their username and password.

Prerequisites

Before migrating, ensure that you have performed and met the following prerequisites:

  • Perform a backup of your system as described in About Backup and Recovery.

  • Ensure that your environment meets all of the system and network requirements described in About Minimum System Requirements

  • Enable TCP ports 5973, 3022, 7373 intra-node to enable communication with the database cluster.

  • Ensure you have permission to run the sudo command on the node where you launch the migration tool.

  • Ensure the kubectl command is available in the node where you are performing the migration. To verify that kubectl is installed, run the following:

    $ sudo gravity enter
$ kubectl

To Perform the Upgrade

  1. Obtain the installer from your customer support representative.

  2. Use ssh to login to one of the nodes of your cluster.

    Performing these procedures from a single node updates the entire platform.

  3. Uncompress the gzip archive.

    tar -xvf anypoint-1.5.2-installer.tar.gz

  4. Navigate to the anypoint-1.5.2 directory, then run the upload script.

    sudo ./upload

    This command updates the platform to the current version and restarts each pod in the cluster.

    $ sudo ./upload
sudo: ./upload: command not found
[centos@ip-172-31-0-97 ~]$ cd 1.5.2/
[centos@ip-172-31-0-97 1.5.2]$ sudo ./upload

    Depending on your network configuration, this command may take a while to complete. Wait until the command finishes before proceeding to the next step.

  5. Ensure that all instances of the gravity component are running by entering the following command:

    $ sudo gravity enter
$ kubectl get pods --namespace=kube-system

    This command displays output similar to the following:

    Ensure that each of the gravity-site-* instances is running before proceeding to the next step.

  6. Login to the Ops Center, then click the Updates tab.

  7. Click Update to this version to update the Anypoint Platform.
