Migrating a Canopy instance's data and files from one server to another

NOTE THAT THESE ACTIONS WILL DELETE ALL DATA ON THE TARGET SERVER

Exporting on source server(as root):

1. Stop Canopy: 

   systemctl stop canopy canopy-celery

   Note for older versions(3.0) of Canopy one would use `supervisord` instead of `systemd`

2. Create DB dump: 

   canopy-manage dumpdata --all -o db.json

   
   

3. Archive uploaded files: 

   tar -zcvf canopy_files.tgz /var/opt/checksec/canopy

   
   

4. Start daemons again if required. 

   systemctl start canopy canopy-celery

   
   

5. Copy db.json and canopy_files.tgz to Server B

Importing on target server(as root):

1. Stop Canopy: 

   systemctl stop canopy canopy-celery

   
   

2. If database structure is outdated or non-existent then configure a production DB: 

   canopy-manage setupdb --prod --drop-tables

   
   

3. Delete data in DB: 

   canopy-manage flush

   
   

4. Remove remaining remnants that are autogenerated:

   Note this may delete files in /var/opt/checksec/canopy/ if their respective objects are still in the DB 

   echo -e 'from django.apps import apps\nfor model in apps.get_models(): model.objects.all().delete()' | SKIP_PRBAC_CHECKS=1 canopy-manage shell

   
   

5. Load db.json: 

   SKIP_PRBAC_CHECKS=1 canopy-manage loaddata db.json

   
   

6. Extract Canopy files: 

   tar -xvf canopy_files.tgz -C /

   
   

7. Set ownership of files: 

   chown -R canopy: /var/opt/checksec/canopy

   
   

8. Start Canopy: 

   systemctl start canopy canopy-celery
