Upgrade 5.3.2 to 5.9: Upgrade in place v New Server
I need to upgrade our installation of ePO 5.3.2 to 5.9. It's on an Win 2008R2 machine, so ePO will evenutally need to be reinstalled on a 2012 or 2016 server. Would it be better to installed 5.9 on a fresh 2012 or 2016 server now, or upgrade 5.3 in place on the 2008 server? What would the implact to the SQL backend if a new installation would be the choice?

You would need to ensure your version of sql is also supported by epo 5.9.1. I would recommend using the migration feature of epo. That allows you to move the system to a new server and OS while at the same time upgrading it. If you do that, you would want to keep servername or IP address the same so as to not break communication and make sure dns resolves the new server correctly for the agents. If you need to restore a backup of the existing database to a new sql server, you can do that first, then point the migration upgrade to the restored database so it gets upgraded properly.
Please be sure to have all required backups, a current, successful snapshot recovery task run and follow KB71825 as well as running the pre installation auditor tool.
If you installed epo new, it would create a new database with new servername, so the existing database would have no impact.
