Examining leakage/move of cases between two cluster analysis solutions

I am looking for the right type of analysis for the following issue.
I have conducted two different types of cluster analysis on the same sample and variables.
Inevitably, some cases have moved from the one cluster to the other.
HOW can I observe this differences?
Namely, three people who were on Cluster 1 in the first analysis moved to Cluster 5 in the second one.

It's a little confusing because the independent is nominal (the clusters as if in within design) and the dependent is scale, is that a two-way ANOVA or regression with dummy coding?
Is the answer going to be given from the post-hoc tests of the ANOVA?
