 !!! note
     Data Controller does NOT modify schemas! It will not create or drop tables, or add/modify columns or attributes.  Only data _values_ (not the model) can be modified using this tool.
 
 To caveat the above - it is also quite common for customers to use a BASE engine library.  Data Controller ships with mechananisms to handle locking (internally) but it cannot handle external contentions, such as those caused when end users open datasets directly, eg with Enterprise Guide or Base SAS.

+## Redeployment
+
+The full redeployment process is as follows:
+
+* Back up metadata (export DC folder as SPK file)
+* Back up the physical tables in the DC library
+* Deploy a brand new instance of DC
+  * To a new metadata folder
+  * To a new frontend folder (if full deploy)
+* _Delete_ the **new** DC library (metadata + physical tables)
+* _Move_ the **old** DC library (metadata only) to the new DC metadata folder
+* Copy the _content_ of the old `services/public/Data_Controller_Settings` STP to the new one
+  * This will link the new DC instance to the old DC library / logs directory
+  * It will also re-apply any site-specific DC mods
+* Run any/all DB migrations between the old and new DC version
+  * See [migrations](https://git.datacontroller.io/dc/dc/src/branch/main/sas/sasjs/db/migrations) folder 
+* Test and make sure the new instance works as expected
+* Delete (or rename) the **old** instance 
+  * Metadata + frontend, NOT the underlying DC library data
+* Rename the new instance so it is the same as the old
+  * Both frontend and metadata
+
+If you are unfamiliar with, or unsure about, the above steps - don't hesitate to contact the Data Controller team for assistance and support.
