"How do I transfer my script to another server"

Problem: You want to use ATC Radar on a different server that you own.

Cause: The resource must remain connected to the purchasing account's entitlement.

Solution: Download the asset through the purchasing account and install that copy on the other server you own. Do not transfer, resell, or share the files or account access with another owner.

FiveM states that an escrowed asset can be used on servers owned by the entitled account. See the official Asset Escrow documentation.
