How long will it take to set up a full server migration – for example: migrating an instance that contains Apache with MySQL?

A properly created VAA can simply be copied and run. The VAA size is roughly the size of the installed application after compression. Apache and MySQL are not too large and the setup time generally is dictated by the small amount of time it takes to move the compressed VAA across the network in use. Compressing and uncompressing the VAA as part of the transfer might take 30 seconds or so depending on CPU speed and disk throughput.
