   @cloud-fan Thanks !! I did wonder about cross catalog operation as well. I have a question -
   Below is the description of the function ```CreateTableLikeCommand```
   ```
   /**
    * A command to create a table with the same definition of the given existing table.
    * In the target table definition, the table comment is always empty but the column comments
    * are identical to the ones defined in the source table.
    *
    * The CatalogTable attributes copied from the source table are storage(inputFormat, outputFormat,
    * serde, compressed, properties), schema, provider, partitionColumnNames, bucketSpec.
    *
   ```
   So in the case where source is a V1 table and target is a V2 table, we are not able to copy some of the V1 metadata like serde, compressed, inputformat, outputformat etc. Right ? Is that okay ?
