Can I use Total Upkeep to transfer a 50GB Multisite network?

Hello Peter-

Thanks for the interesting question, and thanks for considering Total Upkeep to transfer your WordPress Website.

While Total Upkeep does back up your entire Multisite network, including for transfers, you should keep in mind that it will be limited by the resources and PHP limits on both your origin server and the destination server. For a network that large, you’ll need a good amount of resources including Disk I/O, Memory, CPU usage as well as big limits on PHP Execution Time, memory limits, and other settings.

In your case, I’d recommend investigating manual migration techniques, such as Linux’s rsync command, which are more suited for transferring large amounts of data securely.
