 ### Known Issues
 
 #### Custom replacements of default repositories
@@ -74,15 +88,6 @@ you can use the following script to recreate the package default alternatives:
 rpm -qa --scripts java-{1.8.0,11}-openjdk-{headless,devel} | sed -n '/postinstall/, /exit/{ /postinstall/! { /exit/ ! p} }' | sh
 ```
 
-#### IPA fails to start after migration
-
-This issue is caused by a version mismatch due to the way that modules work that
-trick ipa into thinking that the package was downgraded even if it was not.  To
-fix this issue run the following command after migration:
