Update ep 5.4 to 6.4

Hi, can anyone tell me how to update an ep 5.4 to 6.4 or 6.4? For more that I look I do not find it right like doing it .. thanks

its a long way to go if you want to update your EP5 client to EP6 but instead let your players re download your new updated EP6.4 client more easy and simple way to do server upgrade

The server is still creating it but I have it in version 5.4 but I want to take it to 6.3 or 6.4 before putting it in the vps, so if I should start from 0 to 6.4 I would not mind
