Duplicator Lite: Does not support Multisite.
Duplicator Pro: Includes the following Multisite duplication modes.
Multisite Basic
1. Full Network Duplication Since 2.0 | Requires “Duplicator Pro Personal” or above
This allows users to copy/move your entire Multisite installation, rather than backing up or moving individual subsites within the network. For example, if you had a 10 subsitemultisite setup, all 10 sites could be moved and restored as a new Multisite installation in one shot to a new location.[User Guide]
Multisite Plus
2. Subsite > Standalone Since 3.0 | Requires “Duplicator Pro Business or Gold”
This allows users to install an individual subsite within a Multisite network as a standalone site. For example, if you had a 10 subsite WordPress multisite, you can select just one of those sites to restore to be a new standalone site. This process could optionally be repeated 9 more times on different sites to create a total of 10 individual websites from the single Multisite install. [User Guide]
3. Standalone > Subsite Since 4.0.5 | Requires “Duplicator Pro Business or Gold”
This allows users to take a full standalone WordPress site and integrate it into a Multisite network. For example you may have dozens of WordPresssites that you manage and you want to pull them all together into one Multisite network for easier management.[User Guide]
4. Subsite > Subsite [Different Network] Since 4.0.5 | Requires “Duplicator Pro Business or Gold”
This allows users to take a Multi-site subsite and add it into a different Multisite network as a subsite. For example you may have several subsites of a Multisite networkthat you to move into a separate Multisite network but only want to move specific subsites.[User Guide]
5. Subsite > Subsite [Same Network] Since 4.0.5 | Requires “Duplicator Pro Business or Gold”
This allows users to take a Multi-site subsite and add it into a different Multisite network as a subsite. For example you may have several subsites of a Multisite networkthat you to move into a separate Multisite network but only want to move specific subsites.[User Guide]
Subsite Installs:Currently adding a subsite requires the install process to be run for each subsite. So if you currently have 20 subsites you want to move into another multisite network theinstaller will need to be run 20 separate times. In future version we plan to have this processnarrowed down to just one installer run.
Duplicator Pro currently supports the scenarios above for Multisite, however we are continually working to improve the product. For a list of upcoming featuresand possible time-lines please visit the Duplicator Pro Roadmap which discusses additional Multisite features.
