how do i move all the gis authorizations to new computer
What licenses do you have? Normally you would de-authorize the licenses using the license administrator and authorize the new installations afterwards using my.esri.
As Xander mentioned, it would help to know what software and versions. Also, if licensed as a single-user or concurrent license, and if a student, trial, or personal use (annual) license. All may have slight differences.
If Pro only, and using arcgis Online to authorize (and it is not checked out for offline), you should just be able to install on the new machine and login to AGOL on the new machine.
if Desktop, make sure to Deauthorize before you uninstall the software, but there are hints in thus other thread on deauthorizeing https://community.esri.com/message/734381-i-need-to-move-my-arcgis-105-software-from-one-computer-to-another
if it is a license thru a university, you may need to take to the license administrator there.
