Hi there,
To help you move from Performance Analytics to Platform Analytics, ServiceNow created Migration Center. A tool that helps you transition with less effort. While using Migration Center at two customers, or wanting to use it, I stumbled upon an annoying issue... "Page Not Found" when selecting the Migration Center module.
It is a small thing, though good to know, and since I've experienced this at two customers now, most likely a lot more people will face this.
Let's have a close look at the "Page Not Found" issue.
Migration Center
Before using Migration Center on an upgraded instance, most likely you would upgrade plugin "sn-appp-par-coreui-migration-center" (sn_par_mig_center) first. After that, the most conventional way to open the Migration Center is through "Performance Analytics > Migration Center".
Doing so, at two customers I've now experienced that when selecting the Migration Center module, "Page Not Found" displays while opening "now/platform-analytics-workspace/migration-center".
Reading the ServiceNow Product Documentation, the only prerequisite for using Migration Center is that System Property "glide.ui.polaris.experience" should have a value set to "true".
UX Application
The page that is not found is a UX Application. Investigating these, if you are experiencing the same issue, you will find a record with title "Platform Analytics Workspace". Detail though... with "Active" is "false". Okay, clear why the "Page Not Found" is shown 😀.
Though why is the record not active? Comparing the record with PDI initially, I didn't find anything based on the title, so searching based on the Sys ID (08c73d60537101100834ddeeff7b1287). Immediately a few differences stand out: The "Title", "App Shell UI", and "Active" fields have different values.
Skipped Record
As confirmation viewing the "Updates", and "Updated" tells what you already know from the above: a difference in versions. How would that be possible, if you have also upgraded the plugin? Viewing the Update Versions of the UX Application record tells... the Current version is NOT the latest version that was recorded on the instance!
You could also confirm this by viewing the Upgrade details for "sys_ux_page_registry_08c73d60537101100834ddeeff7b1287". The latest version was "Skipped".
Migration Center
Revert to the latest version that was recorded and open the "now/platform-analytics-workspace/migration-center" page again: Issue solved!

And that's it. Not much to it... once you know it 😀. Hopes this helps others a bit when encountering the same issue.
And that's it actually. Hope you like it. If any questions or remarks, let me know!
