Move SEP 11 to new server and then upgrade to SEP 12.1

Hello and Happy New Year to all.

I want to move to new server running Win2008R2 and upgrade my SEPM to the latest version.

According to the following article, the version installed to the new server must be the same version as on the old server.

The running SEPM is the version 11.0.5002.333 and when i go to Symmantec connect and add the serial, it gives me the option to download version 11.0.7300. There will be a problem if the new server has version 11.0.7300 and the old one version 11.0.5002.333 or i must update the old server to 11.0.7300 first and then follow steps of the article?

Thank you
