How to Upgrade ServiceNow Version?
Upgrading ServiceNow version is done in simple steps, but it is a very responsible job to perform because there are lots of other thing which has to be taken care before upgrade.
When we think to upgrade ServiceNow release older version to newer ServiceNow release version, then there are some questions which always bothered that what will happen to the existing functionality, Groups, Users, Customization, Existing Data or Records etc. So, it is a very responsible job to upgrade ServiceNow release versions.
So, there are some suggestions which has been provided by ServiceNow before upgrading the ServiceNow release version, for detail you can navigate to ServiceNow docs.
As per me, it is basically a to-do list to ensure a safe and effective upgrade. So, when we plan to upgrade ServiceNow release version then we should do below:
- Read the release notes carefully which is provided by ServiceNow for every release.
- Basically, release notes provide information that what all fixes has been provided by the ServiceNow in upgraded version and Release notes tell about the new functionalities introduced in new upgrade etc
- Do preparation for testing activities such as test plan, test cases etc. Which has to be executed once the upgrade has been done.
- Most important thing is never upgrade Production instance directly. First upgrade the lower instances. Lower instances are Sandbox, Test, Dev. First clone the lower instance with the production instance and then ask for the updgrade on the selected lower instance.
We can perform ServiceNow release version upgrade one by one on each and every instance, at least do it for two lower ServiceNow instance. Start from Test Instance — then Dev. Instance and then at last upgrade the production instance.
And make sure that after each and every instance upgrade perform smoke testing to ensure that after upgrading the ServiceNow release version functionalities are working fine on not.
