Powershell Script to move Profile, Mapped Drives, Printers, and Files

You can migrate a lot of things, but certain things could/should be configured in the domain.
- Drive mappings should be set using Group Policy or login scripts, Homedirectory can be mapped in the account settings of the user in Active Directory
- Printers can be added by the user themselves using Add Printer, Search and you could configure a Group Policy to automatically select Active Directory published printers. It's just a search and double-click action for the user to select and add the printer
- Bookmarks can be in the user profile within the browser (Google Chome or Edge)
- You could use MDT in combination with User State Migration tool (https://docs.microsoft.com/en-us/windows/deployment/usmt/getting-started-with-the-user-state-migration-tool) to backup the user profile and restore it while imaging new machines?

Inventory of the applications is something you could do with scripting (Something like https://social.technet.microsoft.com/wiki/contents/articles/54279.how-to-create-a-software-inventory-report-using-powershell-step-by-step.aspx). For the DHCP reservations you can inventory the old computer names and let the new computers receive a DHCP lease and convert it to a reservation using the old ip-address (Remove the previous reservation just before that moment)
