Mid Server Migration to Azure Cloud

[Hafeez]

Hi,

All my mid servers will be migrated to Azure Cloud. So would like to know what are important steps and considerations to be noted?

Based on the experience, can someone share their experiences and insight as in:

1. Any known limitations or impact to call out for?
2. What configuration changes need to be done within ServiceNow if a new mid-server is spin up i.e. will there be any manual steps that needs to be performed on the new mid servers?
3. Any document or links would be helpful? I was able to find 

I understand external teams viz., third part applications(in case of integrations), network/infra team’s involvement would be equally important.

Regards,

Hafeez

as i understood from Point 2 - It will be new MID Server - Correct. In this case you need to follow the basics for making changes at all integration points where you old mid servers are used. Treat this a fresh installation.

I would echo this, this needs to be treated as three separate positions.

1. Provisioning of new MID servers, verification of clustering, capabilities, applications, IP ranges etc. and confirmation they can operate as expected.

2. Transition of workload, as well as ITOM, don't forget Integrations, export sets and LDAP/JDBC data feeds can use MIDs.

3. Monitor the ecc queue for any transactions on the old MID servers to verify that you have migrated all the workloads.

Once you have confirmed the above, I would recommend to stop the old MID servers for a time and ensure nothing breaks before fully decomissioning them. If you have any monitoring set up on the old MID processes themselves then you would obviously want to stop that at the same time.

Hope it goes well!

Determine the compatibility of the mid server with Azure Cloud. Identify the resources, dependencies, and configurations that need to be migrated to Azure Cloud.

Create a migration plan that includes timelines, migration methods, and testing. Ensure that all stakeholders are involved and informed of the migration plan.

Create an Azure environment that matches the mid server environment. This may include virtual machines, storage accounts, and network configurations.

Configure the Azure environment to match the mid server environment. This may include setting up network security groups, configuring load balancers, and setting up domain name servers.

Install the mid server software on the Azure virtual machine. Ensure that the mid server software is configured to connect to the appropriate systems and applications.

Test the mid server to ensure that it is functioning as expected. This may include testing connectivity, testing workflows, and testing integrations.

Once the mid server has been tested and verified, redirect traffic from the old mid server to the new mid server in Azure Cloud.

Monitor the mid server in Azure Cloud to ensure that it is performing optimally. This may include monitoring resource utilization, monitoring logs, and optimizing configurations.
