Import Method - Do you know how to import a solution if you don’t have the original installer? (optional)

You should have at this point, either:

1. Installer packages from 3rd Party Vendors for installing their custom solution or,
2. WSP packages from 3rd party, or built from your own source code, or extracted using the Export Method (not recommended)

You can add the WSP package solutions to the new server by:

1. Open up cmd with Administrator privileges
2. Enter your C:\SharePointCustomizations folder
   cd C:\SharePointCustomizations
3. Use stsadm to import the solution to your new server
   Stsadm –o AddSolution –filename NameOfSolution.wsp
4. Make sure there are no errors when the command runs
