Now we can start the migration. On the First Page you can now select if it’s a new environment or a migration. The migration will be next to each other so the old and the new appliance will keep collecting data until you decide your migration is successful. If not just start over.

Now you have to select you source server. This is the ip address of you UI VM not the analytics VM ip address. Click Add source. You will get an info pop-up screen with the information it will take 5 min.
If you installed any solutions on the 5.8 appliance, for example Log insight or hyperic, you will need to update these first.

Download the missing solutions from https://solutionexchange.vmware.com/store and click add solution to update them. When all solutions are green status then click next.
