 Due to the nature of how Cloud.gov operates, the getgov directory is dynamically generated whenever the app is built under the tmp/ folder.

From here, we can move those uploaded files into the getgov directory using the `cat` command. Note that you will have to repeat this for each file you want to move, so it is better to use a tar.gz for multiple, and unpack it inside of the `datamigration` folder.

-**SETUP**
-In order to use the management command, we need to add the files to a folder under `src/`.
 This will allow Docker to mount the files to a container (under `/app`) for our use.  
 
  - Create a folder called `tmp` underneath `src/`
  - Add the above files to this folder
  - Open a terminal and navigate to `src/`
 
-Then run the following command  (This will parse the three files in your `tmp` folder and load the information into the TransitionDomain table);
+#### You are now ready to run migration scripts (see "Running the Migration Scripts")

+### RUNNING THE MIGRATION SCRIPTS
+
+**NOTE: Whil we recommend executing the following scripts individually (Steps 1-3), migrations can also be done 'all at once' using the "Run Migration Feature" in step 4.  Use with discretion.**
+
+#### 1 - Load Transition Domains
+Run the following command  (This will parse the three files in your `tmp` folder and load the information into the TransitionDomain table);
 ```shell
-docker compose run -T app ./manage.py load_transition_domain /app/tmp/escrow_domain_contacts.daily.gov.GOV.txt /app/tmp/escrow_contacts.daily.gov.GOV.txt /app/tmp/escrow_domain_statuses.daily.gov.GOV.txt

+### STEP 3: Send Domain invitations
+### Run the send invitations script
+
+To send invitations for every transition domain in the transition domain table, execute the following command:
+`docker compose run -T app send_domain_invitations -s`
+
+### STEP 4: Test the results
+### Run the migration analyzer
+
+This script's main function is to scan the transition domain and domain tables for any anomalies.  It produces a simple report of missing or duplicate data.  NOTE: some missing data might be expected depending on the nature of our migrations so use best judgement when evaluating the results.
+
+**ANALYZE ONLY**
+To analyze our database without running migrations, execute the script without any optional arguments:
+`docker compose run -T app ./manage.py master_domain_migrations --debug`
+
+**RUN MIGRATIONS FEATURE**
+To run the migrations again (all above migration steps) before analyzing, execute the following command (read the documentation on the terminal arguments below.  Everything used by the migration scripts can also be passed into this script and will have the same effects).  NOTE: --debug and --prompt allow you to step through the migration process and exit it after each step if you need to.  It is recommended that you use these arguments when using the --runMigrations feature:
+`docker compose run -T app ./manage.py master_domain_migrations --runMigrations --debug --prompt`

+- contacts_filename is the Data file with contact information
+- domain_statuses_filename is the Data file with domain status information
+
+`--sep`
+Delimiter for the migration scripts to correctly parse the given text files.
+(usually this can remain at default value of |)
+
+`--debug`
+A boolean (default to true), which activates additional print statements
+
+`--prompt`
+A boolean (default to true), which activates terminal prompts
+that allows the user to step through each portion of this
+script.
+
+`--limitParse`
+Used by the migration scripts (load_transition_domain) to set the limit for the
+number of data entries to insert.  Set to 0 (or just don't use this
+argument) to parse every entry. This was provided primarily for testing
+purposes
+
+`--resetTable`
+Used by the migration scripts to trigger a prompt for deleting all table entries.
