 ##### @patternfly
 
 Note that when upgrading @patternfly packages, we've seen in the past that it can cause the JavaScript heap to run out of memory, or the bundle being too large if multiple versions of the same @patternfly package is pulled in. To increase efficiency, run the following after updating packages:
 
 ```
-yarn run dedupe-deps --scopes @patternfly
+yarn dedupe --strategy highest
 ```
 
 Please note that PatternFly releases do not strictly follow semantic versioning. Therefore, it's important
