WSUS 3.0 Clustering question

currently have 3 wsus3.0sp2 servers running, , doing perfectly. each server @ different physical location, own wsus db, which serves updates specific location (all within same domain). clients @ each site connect respective wsus server defined in our gpo. servers sync from upstream server connected internet. to schedule/push patches @ each site, have 3 servers.

i have been tasked attempting implement solution have schedule installs once (instead of 3 times). after reading clustering section of operations guide seems way it, want check if way higher-ups want work. say, still have 1 server per physical location (for 3 servers total), these clustered in 1 wsus 3.0 cluster shares 1 wsus db. in way, approve patches cluster , clients download them respective site's server before. how wsus clustering can work?

thanks.

hi, think maybe what wanting here implement replicas

replicas approvals and/or updates upstream server. have @ wsus deployment guide , search on word replica.
