Migration with docker

We have changed the machine but not the hard drive or the IP address.
However, we are unable to connect AMP to the new machine.
Here is the error:
docker: Error response from daemon: Conflict. The container name “/AMP_LaResistenza-LiniziodiunanuovaEra01” is already in use by container “be11a080d1cf006a00cff88d2718264c6745d0069dd9d87ef856a24d4d484b00”.

Can you help me?
