What is parallel export?
Parallel export is the process of doing exports simultaneously in a multisite environment.
Does the Prime Mover plugin support parallel export in a multisite setup?
Yes, the plugin is tested to work with parallel export. This means that in a multisite setting, you can export subsites simultaneously, and it should work fine.
What are the limitations of Parallel export?
Parallel export is only limited by your server resources. Since exporting can consume RAM, CPU, and disk space, be careful when running parallel exports, as they will consume significant resources! Your site’s backend and frontend might become very slow due to heavy resource usage.
Do you recommend doing parallel export in multisite?
Since Prime Mover 2.1.6+, parallel export is now fully supported in multisite, as long as you have sufficient server resources to support it. If you are on a shared host, it is recommended to do this conservatively, such as by running 3 simultaneous exports to prevent your server from overloading. Or at worst, if you already have an underperforming server, don’t do this at all!
What is a parallel import?
Parallel import is the process of restoring packages simultaneously in a multisite environment.
Does the Prime Mover plugin support parallel import in a multisite setup?
Yes, since Prime Mover 2.1.6+, the plugin is fully updated to support multisite parallel/concurrent or simultaneous imports. So you can restore several subsites simultaneously and save time. As with exporting, the only limitation is your server resources, such as disk space, RAM, or CPU. In our tests, the optimal number of sites to restore (at the same time) for a reasonable server is around 5. If your site server is underperforming or slow, please don’t do a parallel restore. You should only restore one site at a time.
