Hi @Michael Williams ,
Please follow the below steps:
- Ensure that you have enough space available on the server.
- Open SharePoint PowerShell and ensure that you are running it as administrator.
- First take backup of the source site collection as below:
Backup-SPSite https://source-sitecoll-url -Path "C:\Backup\sourcesitecollection.bak"
This command will take the backup of the site collection and store it inside the `bak` file on the server.
- After that create a new web application (skip this if already created).
- Now create an empty site collection in the new web application.
- After that you can restore it as below:
Restore-SPSite https://destination-sitecoll-url -Path "C:\Backup\sourcesitecollection.bak" -Force
This will restore the site collection from the backup file. Here, `Force` parameter is optional.
