If the TKr content library reaches capacity, you can migrate to a new content library with more storage capacity.
When the vSphere administrator creates a content library, the administrator specifies a datastore for storing library contents, in this case OVA files. Over time as more Kubernetes versions are distributed, the content library will expand in size as OVA files are added for each update. While there is no explicit capacity on the content library, it is limited by its datastore capacity.
If the content library reaches capacity, you might see the message Internal error occurred: get library items failed for.
In this case you can migrate TKG clusters to a new content library to increase storage capacity. The migration is done using the vSphere Client.
