+The powerBI db backup pipeline was migrated from the old paas environment to the new aks environment
 
+the old pipeline was implemented using azure devops classic release pipeline.
 The new pipeline is also implemented using the classic azure devops release pipeline and it is located here
 https://dev.azure.com/dfe-ssp/S105-School-Experience/_release?_a=releases&view=mine&definitionId=66
 
 the pipeline works by doing a backup of the kubernetes application database in aks. The database is accessed byport forwarding using Konduit.
 
+There are two set of credentials used in the pipeline namely admin and perfappuser
+the admin credentials is used in deleting and recreating the perf analysis database
+This is the admin credentials created when the db was initialised
+
+the perfappuser credentials is used when importing the database and this is created when the perf analysis database is
+being created
+
 konduit is installed using the make file from the repository
 
 a dump command is then run on the postgres database to dump the db into a file on the pipeline
 the command that is run is
 ``bin/konduit.sh  -k $(KV) -d gse-production get-school-experience-production  -- pg_dump  -E utf8 --clean --if-exists --no-owner --verbose --no-password  -f  schoolexperiencedb_temp.sql``
 where kv is the keyvault name, -d option refers to the database name, and get-school-experience-production  refers to the pod name
 
-the performance db is then deleted and recreated in the next task and the exported db in schoolexperiencedb_temp.sql  is then imported into the performance database
+the performance db is then deleted and recreated in the next task and the exported db in schoolexperiencedb_temp.sql  is then imported into the performance database. the recreation is done using the script available at
+https://raw.githubusercontent.com/DFE-Digital/school-experience-devops/master/createdb.sql
+in this script the perfappuser credentials is used using the password variable 'postgresUserPassword' that is stored in the pipeline
+perfappuser credentials is used in the data source
 
 ogr2ogr is also used to load GeoJSON files (eer.json and topo_lad.json) into the PostgreSQL database
