At our company, we are currently changing our servers, both names and locations. When doing so, will we need a new ModelSim license file, or can we just go with the same file as before?
If your current licenses are floating and attached to the MAC address as the server 'hostid', then assuming the new server has a different MAC address then yes, you will need to request a new license. If your licenses are attached to a USB key then no license regeneration is required.
Here is a link for opening a new Service Request that will route to the correct team that can action the license transfer. Just be sure to include both your current and new MAC address/hostid. Determining the Hostid for Licensing
