Network migrations: benefits and impacts

Benefits of Pega Cloud Services network migration

Changes to your environments take effect following the network migration. The benefits of the enhanced network to the infrastructure include the items detailed below:

• Use of a more reliable and scalable Pega Cloud network infrastructure
• Enhances security of your underlying network infrastructure
• Enhances the stability of the software upgrade and patch and infrastructure update processes

For more information, see Pega Cloud Services maintenance and types of system updates.

Network migration planning considerations

The Pega Cloud network migration impacts you if you have the following allow list configurations:

• Inbound traffic from isolated environment types (Development, Staging, Production) from your Pega Cloud environment to your enterprise network.
• Inbound traffic from fully isolated environments of the same type (Development 1, Development 2) in your Pega Cloud environment to your enterprise network.
• Outbound traffic from your enterprise network to the Pega Cloud SFTP service to your Pega Cloud environment.

Pega Cloud Services proactively contacts you to plan the network migration to the new network topology. This communication includes a questionnaire that Pega uses to determine if you use the above allow list configurations. In order for the migration to proceed, you must reconfigure these allow lists. To see the questionnaire, see Preparing for the network migration questionnaire below.

For more information about allow list configurations, see Configuring public access between your Pega Cloud environment and your enterprise network.

You should plan to complete the following processes in order to proceed with the migration:

• Share the questionnaire with your enterprise network administrator and other relevant stakeholders to collaborate with Pega Cloud Services in determining allow list reconfiguration requirements for the network migration to proceed.
• Plan for the zero-downtime network migration to proceed within your next standard maintenance window.
• Clients who must reconfigure any of their allow lists must complete the following tasks:
  • Reconfigure your allow lists using the new Pega-provided static IP addresses.
  • Confirm with Pega Cloud Services that you updated your allow lists.
  • Remove previously-used IP addresses for your Pega Cloud environment from the allow list.

If the network migration does not impact your allow list configurations, you still must answer the questionnaire to provide consent for the migration to proceed.

Pega responsibilities

• Coordinates with the client to facilitate any required client-side networking changes to support the network migration.
• Sends you a questionnaire via email correspondence to determine if you require allow list reconfigurations for the migration to proceed.
• If you must reconfigure you allow list, Pega accomplishes the following tasks:
  • Shares a set of new static IP addresses for you to place on an inbound allow list to minimize impact to their network during the migration.
  • If you added your SFTP connection to an allow list, provides the you with a new static IP address for their SFTP service.
  • Confirms with you that new static IP addresses are placed on an allow list.
  • After the migration, shares a list of static IP addresses with you that are no longer associated with the Pega Cloud environment for you to remove from your enterprise network allow list.

Client responsibilities

To ensure the process maintains zero-downtime to transfer Pega Cloud environments to the new network topology, you must perform the following tasks:

• Respond to Pega Cloud Services questionnaire that asks for the required enterprise network information.
• Confirm a standard maintenance window with Pega Cloud Services to execute the network migration.
• For all of your environments that require an allow list reconfiguration, complete the following tasks:
  • Obtain necessary approvals from network administrators and other relevant stakeholders regarding inbound allow list changes to Pega Cloud environments.
  • If you added your SFTP connection to an allow list, update the allow list with the new SFTP static IP address.
  • Prior to the migration, update the allow list with the new Pega-provided static IP addresses.
  • Confirm with Pega that you updated your allow lists.
  • After completing the migration, remove the static IP addresses provided by Pega Cloud Services in the correspondence for your enterprise network inbound allow list.

Preparing for the network migration questionnaire

Pega Cloud Services sends the network migration questionnaire to you. The following table presents the content of the questionnaire and the implication of your reply to the email correspondence. You should review the table to understand which scenarios require network reconfigurations, and what actions you must complete before Pega Cloud proceeds with the migration. If you do not need any allow list reconfigurations must confirm this and approve the migration to proceed with the network migration.

After you provide your network information, Pega Cloud Services can effectively plan and execute a seamless migration process. For frequently asked questions about the network migration, see Network migration Frequently Asked Questions.
