Upgrade from wampserver 2.5 to wampserver 3.0 (1 reply)

We have installed the 64 bit wampserver version 2.5; its current components are Apache 2.4.12; PHP 5.6.15; mySQL 5.6.17
We want to upgrade to 64 bit wampserver version 3.0; Apache 2.4.17; Mysql 5.7.9; PHP 5.6.16_7.0.0

Please point us to instructions as to how we can do this upgrade. Thanks.
