+## 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 metadata 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.
+

+| Argument Name      | Required? | default                                        | Type   | Description                                                             |
+|--------------------|-----------|------------------------------------------------|--------|-------------------------------------------------------------------------|
+| `table`            | ✔️        |                                                | string | Name of the table                                                       |
+| `source_prefix`    | ✔️        |                                                | string | The existing prefix to be replaced                                      |
+| `target_prefix`    | ✔️        |                                                | string | The replacement prefix for `source_prefix`                              |
+| `start_version`    |           | first metadata.json in table's metadata log    | string | The name or path to the chronologically first metadata.json to rewrite. |
+| `end_version`      |           | latest metadata.json                           | string | The name or path to the chronologically last metadata.json to rewrite   |
+| `staging_location` |           | new directory under table's metadata directory | string | The output location for newly modified metadata files                   |
+
+
+#### Modes of operation:
+
+- Full Rewrite:
+
+By default, the procedure operates in full rewrite mode where all metadata files are rewritten.
+
+- Incremental Rewrite:
+
+If `start_version` is provided, the procedure will only rewrite delta metadata files between `start_version` and `end_version`. `end_version` is default to latest metadata location of the table. 
+
+#### Output
+
+| Output Name          | Type   | Description                                                                         |
+|----------------------|--------|-------------------------------------------------------------------------------------|
+| `latest_version`     | string | Name of the latest metadata file rewritten by this procedure                        |
+| `file_list_location` | string | Path to a file containing a listing of comma-separated source and destination paths |
+
+Example file list content :
+
+```csv
+sourcepath/datafile1.parquet,targetpath/datafile1.parquet
+sourcepath/datafile2.parquet,targetpath/datafile2.parquet
+stagingpath/manifest.avro,targetpath/manifest.avro
+```
+
+#### Examples
+
+Full rewrite of a table's metadata path from source location in HDFS to a target location in S3 bucket of table `my_table`.
+This produces a new set of metadata using the s3a prefix in the default staging location under table's metadata directory
+
+```sql
+CALL catalog_name.system.rewrite_table_path(
+    table => 'db.my_table', 
+    source_prefix => "hdfs://nn:8020/path/to/source_table",
+    target_prefix => "s3a://bucket/prefix/db.db/my_table"
+);
+```
+
+Incremental rewrite of a table's metadata path from a source location to a target location between metadata versions
+`v2.metadata.json` and `v20.metadata.json`, with files written to a staging location
+
+```sql
+CALL catalog_name.system.rewrite_table_path(
+    table => 'db.my_table', 
+    source_prefix => "s3a://bucketOne/prefix/db.db/my_table",
+    target_prefix => "s3a://bucketTwo/prefix/db.db/my_table",
+    start_version => "v2.metadata.json",
+    end_version => "v20.metadata.json",
+    staging_location => "s3a://bucketStaging/my_table"  
+);
+```
+
+Once the rewrite is completed, third-party tools (
+eg. [Distcp](https://hadoop.apache.org/docs/current/hadoop-distcp/DistCp.html)) can be used to copy the newly created
+metadata files and data files to the target location
+
+Lastly, after referential integrity check on copied files, [register_table](#register_table) procedure can be used to register copied table in the target location with catalog.
+
+!!! warning
+    Iceberg table with statistics files are not currently supported for path rewrite
