Engine Tab

This option controls how the database is updated when migrating to the new site.

Option	Details
Custom Search and Replace
Overview	Pro Permits adding as many custom search and replace items as needed. Use extreme caution when using this feature as it can have unintended consequences as it will search the entire database. It is recommended to only use highly unique items such as full URL or file paths with this option.
Database Scan Options
Cleanup	Pro The checkbox labeled "Remove schedules & storage endpoints" will empty the Duplicator schedule and storage settings. It is recommended that this remain enabled so that you do not have unwanted schedules and storage options.
Skip Path Replace	This is an advanced option that should be used when trying to install from either the "/" or "/html" location. The following conditions are set with this option when the install location is detected. Source folder is / the parameter should be visible in read-only mode and not checkable. Source folder is /html the parameter must be check by default and kept checked. In other cases, the parameter must be inactive by default and checkable. This option helps to resolve issues when the install path is either "/" or "/html". In case the source path is /html this option is required to prevent data update conflicts. For example the html_type option in the wp_options table with data such as text/html is replaced with text/[new_path] which can lead to other issues therefore this option is required to be checked to prevent those types of database update issues.
Email Domains	The domain portion of all email addresses will be updated if this option is enabled.
Database Search	Database full search forces a scan of every single cell in the database. If it is not checked then only text-based columns are searched which makes the update process much faster. Use this option if you have issues with data not updating correctly.
Cross Search	Pro This option enables the searching and replacing of subsite domains and paths that link to each other within a Multisite network. Check this option if hyperlinks of at least one subsite point to another subsite. Uncheck this option there if there are at least subsites and no subsites hyperlinking to each other. Note: Checking this option in this scenario would unnecessarily load your server. Check this option if you are unsure if you need this option.
Post GUID	If you're moving a site keep this value checked. For more details see the notes on GUIDS . Changing values in the posts table GUID column can cause RSS readers to evaluate that the posts are new and may show them in feeds again.
Serialized Max Size	Large serialized objects can cause a fatal error when Duplicator attempts to transform them. If a fatal error is generated, lower this limit. If a warning of this type appears in the final report: DATA-REPLACE ERROR: Serialization ENGINE: serialize data too big to convert; data len: XXX Max size: YYY DATA: ..... and you think that the serialized object is necessary you can increase the limit or set it to 0 to have no limit.
