> Currently, rename table/partition updates the data location by renaming the directory which is equivalent to moving files to new path and delete old path. So, this should trigger move of files into $CMROOT.
> Scenario:
> 1. Create a table (T1)
> 2. Insert a record
> 3. Rename the table(T1 -> T2)
> 4. Repl Dump till Insert.
> 5. Repl Load from the dump.
> 6. Target DB should have table T1 with the record.
> Similar scenario with rename partition as well.
