OpsCenter Analytics Server Merge

Need to create a new large Server to take over the existing four Opscenter Servers. I will need to keep the historical data..

Currently three of the four OpsCenter Severs are at 7.1.0.4 and the fourth one is at 7.5.. I know that I would have to make all four servers at a current release.. 7.5.0.5.. 

Once the new OpsCenter server has been Built. Can I take and merge the four server database, reports, etc to the one server..
