IoT GreenGrass: the latest greengrass-nucleus-latest(2.11.1) dos not support lattest IDT 4.7.0

Question

I am using below cmd to install in my Device wich is installing the latest greengrass nucleus.

curl -s https://d2s8p88vqu9w66.cloudfront.net/releases/greengrass-nucleus-latest.zip > greengrass-nucleus-latest.zip && unzip greengrass-nucleus-latest.zip -d GreengrassInstaller
sudo -E java -Droot="/greengrass/v2" -Dlog.store=FILE -jar ./GreengrassInstaller/lib/Greengrass.jar --aws-region eu-central-1 --thing-name TeraGreengrass --thing-group-name GreengrassQuickStartGroup --component-default-user ggc_user:ggc_group --provision true --setup-system-service true --deploy-dev-tools true

But when we are trying to validate the device using IDT version devicetester_greengrass_v2_4.7.0_testsuite_2.5.0_win , it throws a version-compatible issue.

Host : window
Device: ubuntu aarch64

Now I want to downgrade the Greengrass-nucleus to 2.11.0 wich is supported by IDT tool.
I have already attempted several processes but have not achieved any results.
Your assistance would be greatly appreciated.
Thank you in advance.

Hello Kamalnath,

For new Greengrass Nucleus releases, IDT is currently only supporting ```major.minor.0``` versions. See [here](https://docs.aws.amazon.com/greengrass/v2/developerguide/idt-support-policy.html) for more information.

For your case I would suggest removing and re-installing the nucleus on the device using the correct version.
```
curl -s https://d2s8p88vqu9w66.cloudfront.net/releases/greengrass-2.11.0.zip > greengrass-2.11.0.zip
```

Joseph
