+## Table Replication
+
+The `rewrite-table-path` assists in moving or copying an Iceberg table from
one location to another.
+
+### `rewrite-table-path`
+
+This procedure writes a new copy of the Iceberg table's files where every path
has had its prefix replaced.
+The newly rewritten metadata files, along with data files, enable moving or
coping an Iceberg table to a new location.
+After copying both metadata and data to the desired location, the replicated
iceberg
+table will appear identical to the source table, including snapshot history,
schema and partition specs.
+
+!!! info
+ This procedure only creates metadata for an existing Iceberg table
modified for a new location. Procedure results can be consumed for copying the
files.
+ Copying/Moving metadata and data files to the new location is not part of
this procedure.
