Problem
Updating Jira Cloud Migration Assistant might disable Analytics Client Plugin somehow and prevent users from using this tool as it will only return a blank screen without further details.
Diagnosis
On the front-end, the request below will fail when trying to access JCMA's home page:

"status-code": 500,
"stack-trace": "org.eclipse.gemini.blueprint.service.ServiceUnavailableException: service matching filter=[(objectClass=com.atlassian.analytics.api.services.AnalyticsConfigService)] unavailable
}You can also confirm this issue by accessing your atlassian-jira.log files and searching for an error like the one below:

Go to your Manage apps page
Change the filter to show all apps

Version : 6.1.16
Status : disabled
Vendor : Atlassian
Description : Resolution
If Analytics Client Plugin services are disabled, you can just enable it by following the steps below:
Go to your Manage apps page
Change the filter to show all apps
Find the Analytics Client Plugin plugin
Expand it and make sure it's enabled
Restart Jira
That should fix the blank screen issue on JCMA.
