Hey Rohit,
You can extract the ARM template and import it but that would be like copying all the datasets,pipelines etc from 1 ADF to another.
So for your case , you can copy the JSON code from 1 ADF and paste it in another data factory by overriding the code of the newly created dataset or pipeline .
Note: this is copying from 1 ADF to another and not moving it. So you would have to then delete the code from 1st ADF
