License types (computer or named) are chosen at the time of purchase and cannot be changed freely.
However, a one-time license type change request may be possible in specific cases upon review by Hex-Rays. For example, if a team member using IDA moves to another project, you may prefer to assign the license to a specific computer rather than an individual.
To request the change, please contact our Sales team at sales@hex-rays.com.
Note: For greater flexibility in managing users and machines running IDA, we recommend using floating licenses.
