+## DWS Migration Notes
+
+- DWS does not have folder card data so we do not need to run `migrate_folderdata.py`
+- Before running `migrate_filedata.py`
+    # checks in {}config.json
+    - Run the SQL Query `Find_Duplicate_Rows.sql`. This will show us everywhere there are conflicts in the Document Configurations.
+      This will show us all the ConfigID's we have to worry about manually mapping in the `config.json`
+    - Confirm Root Folder = DWS
+- Run `migrate_filedata.py`
+
+## After Migration
+
+# 1. State Transitions
+- Compile CSV lists for the state mappings. Look at the Existing DWS.CSV files for reference.
+- Add the Admin-Transitions to the Drilling Vault production environment so that we can move files directly.
+- We don't need to do anything for WIP, parts that come in as WIP as default
+- Schema
+    VAULTED -> VAULTED
+    RELEASED -> APPROVED
+    CHANGE PENDING APPROVAL -> CHANGE PENDING APPROVAL
+- Run the PDM Transitions using `\config\batch_workflows_paths.py`
+    - EX: **python batch_workflows_paths.py -v {Vault Name} -c {Filename.csv} -t {Transition Name}**
+
+# 2. Variable Copying
+DWS wants to use the existing filecards. The problem is that the Existing filecards use the variable **Drawing Number**. DWS used the variable **Number**
+We can handle this by simply making a copy of the existing data in the `VariableValue` table in SQL. It isn't linked in a complicated web so adding rows doesnt hurt it
+
+EX:
+    VariableID	DocumentID	ProjectID	RevisionNo	ConfigurationID	ValueText	ValueInt	ValueFloat	ValueDate	ValueCache	IsLongText
+          45	24499	       2	        1	          82	      SWR	      NULL	       NULL	1900-01-01 00:00:00.000	SWR	0
+
+**We would just insert this row (only change is VariableID)**
+
+    VariableID	DocumentID	ProjectID	RevisionNo	ConfigurationID	ValueText	ValueInt	ValueFloat	ValueDate	ValueCache	IsLongText
+          75	24499	       2	        1	          82	      SWR	      NULL	       NULL	1900-01-01 00:00:00.000	SWR	0
+
+- use the python file `/helpers/db_helper.py`
+## Note the VariableID's in here are for the Test DB.
+## UDPATE VARIABLE VALUES WITH THE PRODUCTION VALUES
+- First run it with the parameter `python db_helper.py --db target_db --task check_vv50`
+- Once that is complete there should be a csv file `has_vv50_{date}.txt` that shows anything that already has a variable value for **Drawing Number**
+- If that looks good run `python db_helper.py --db target_db --task copy_57_to_50 --dry-run` if you want to run dry-run
