After upgrading from UMP 8.31 to 8.51, getting errors when accessing the UMP page where the deprecated Alarm Console portlet was added:

This portlet has been undeployed. Please redeploy it or remove it from the page.

When attempting to access the UMP USM page, the following pop-up error appears:

java.lan.NoSuchMethodError :

The UMP portal is highly customized in this environment with pages defined that use deprecated UMP portlets.
