Errors while upgrading from CEDR to DRS in Linux AMI 2.0

Question

Getting below mentioned Warning Messages while trying to upgrade from CEDR to DRS in Linux System installed with AMI 2.0.
```
python3 cloudendure_to_drs_upgrade_tool.py start-upgrade --api-token  --project-id  —aws-access-key-id  —aws-secret-access-key  --import-blueprint --import-replication-configuration --import-test-snapshot
Running the CloudEndure to DRS Upgrade tool.
Connecting to the CloudEndure Console... Finished.

Warnings:
- Unable to detect if the Machine's operating system is supported by DRS.
Refer to DRS documentation for the list of supported operating systems (UnableToDetermineOperatingSystemSupport)
- Unencrypted volumes are not supported in DRS.
It is recommended to set an explicit encryption key in your Replication settings prior to performing the upgrade.
Machines with no volume encryption configured will be converted to use the default EBS encryption key in DRS. (UnencryptedVolumesUnsupported)
There are warnings for this machine. Would you like to continue? [Y/n]:n
```
As per below mentioned AWS Doc AL 2.0 is supported by DRS:
[https://docs.aws.amazon.com/drs/latest/userguide/Supported-Operating-Systems.html
]()

Moreover I have set Default key for EBS Volume Encryption in both CEDR and DRS Service.
What should I do fix these warning signs besides the steps which I have taken?

Answer

For your first question, I had asked support about that, and here was their response:

The CEDR to AWS DRS Upgrade Tool was initially developed prior to the recent introduction of AWS-AWS support in AWS DRS. As AWS as a source was not initially supported in AWS DRS, the tool chose to ignore AL/AL2 as valid operating system sources.

The Service Team has chosen not to update this warning in the tool, to date, as it is not a blocker, and given the rapid movement from CEDR to DRS, feel that it's unlikely to be needed.

Regarding the encryption, is it perhaps that the instance you are trying to install the agent on has a volume attached that is not encrypted?
