Cluster version question

[espressobeanies]

How far behind in versioning can ECM-clustered nodes be before the cluster itself breaks?

Thanks!

Not really sure what you mean by being "behind in versioning"... The nodes of the cluster must be of the same Alfresco version to work properly, otherwise any number of issues may occur either during startup of one of the nodes (schema validation) or at runtime (conflicts with schema differences relative to "expectation").
