Do you want to move table or records in that table?

I need to export (XML) data from 1 instance table to another instance on a different table.

Moving one table data to another table using xml is not possible as it contain the table name to be update.

If the table does not exist in that instance, you can move it using an update set.

Check the table creation date from Tables then go to Local update set,using it find all the entry for that table creation in Default update set , Change the update set name to your new updateset name.
