Section "1.2. Scaling managed clusters (Technology Preview)" has the sentence pointing to a broken link:

To scale managed clusters that were imported from other providers, see Provider managed clusters scaling.

My understanding is that the linked content used to exist, but was removed because it was referencing 3rd party documentation on how to scale k8s clusters using hyperscaler instructions.

Ideally we should expand what means to scale an imported cluster and remove the broken link. If not possible to expand on this, we should at least remove the broken link
