Is it possible to change the IP of Office Online Server while it is in production?

Question

Is it possible to change the IP of Office Online Server while it is in production? The OOS is integrated with SharePoint server 2019.

If YES, what measure must be taken before changing the IP of OOS.

Answer 1

Yes, it is possible to change the IP address of Office Online Server (OOS) while it is in production. However, it's important to plan and execute this change carefully to minimize disruptions to your SharePoint Server 2019 environment.

Here are some measures you should consider before changing the IP address of OOS:

Backup: Before making any changes, ensure you have a recent backup of your SharePoint Server environment, including any configurations related to OOS.

Communication: Notify users in advance about the planned maintenance or IP address change to minimize any unexpected disruptions.

Document Dependencies: Identify all dependencies on the current IP address of the OOS. This includes SharePoint Server configurations, DNS settings, firewall rules, load balancer configurations, etc.

Update DNS: If DNS records are used to resolve the OOS hostname, update the DNS records to reflect the new IP address. Ensure the DNS changes propagate properly across your network.

Update Firewall Rules: If there are specific firewall rules allowing traffic to/from the OOS, update these rules to reflect the new IP address.

Update Load Balancer Configurations (if applicable): If OOS is behind a load balancer, update the load balancer configurations to use the new IP address.

Update SharePoint Server Configuration: Update the SharePoint Server configuration to point to the new IP address of the OOS. This may involve updating the Office Online Server URL in SharePoint Central Administration or using PowerShell cmdlets to update the OOS server URL.

Test: After making the IP address change, thoroughly test the integration between SharePoint Server and OOS to ensure everything is functioning as expected.

Monitoring: Monitor the SharePoint environment closely after the IP address change to catch any issues that may arise.

Rollback Plan: Have a rollback plan in place in case any issues occur during or after the IP address change. This may involve reverting to the previous IP address and configurations.

By following these measures and carefully planning the IP address change, you can minimize disruptions and ensure a smooth transition for your SharePoint Server environment integrated with Office Online Server.

Answer 2

Per my knowledge, the IP address of Office Online Server (OOS) should be same with SharePoint server.
