+## Steps of migrations
+
+---
+
+### Backup
+
+1. copy superset db into your local and take backup
+
+```shell
+scp -i ~/.ssh/openchs-infra.pem  ubuntu@reporting-superset.avniproject.org:/home/superset/.superset/superset.db .
+scp -i ~/.ssh/openchs-infra.pem  ubuntu@reporting-superset.avniproject.org:/home/superset/superset_config.py . 
+```
+---
+
+
+### install docker
+1. follow below command to install docker [Official guide](https://docs.docker.com/desktop/install/ubuntu/)
+```shell
+sudo apt-get update
+sudo snap install docker
+sudo chown ubuntu /var/run/docker.sock
+sudo chmod 660 /var/run/docker.sock
+```
+
+
+
+### remove values from superset.db
+
+1. use [/assets/mismatch_data_superset_sqllite.sql](https://github.com/avniproject/avni-infra/blob/master/reportingSystem/superset/assets/mismatch_data_superset_sqllite.sql) to remove the record (currently it is causing issue in primary key)
+
+
+---
+### Upgrate to docker 2.0.1 and postgres
+
+1. create network for superset and run superset(2.0.1)  
+```shell
+docker network create superset_network
+
+docker run -d  -p 8088:8088  --network superset_network  --name superset_2.0.1 apache/superset:2.0.1
+
+docker exec -it  -u root superset_2.0.1 bash
+
+apt-get update && apt-get install vim
+
+vim superset_config.py
+
+export SUPERSET_CONFIG_PATH=/app/superset_config.py
+```
+
+2. paste content of [/assets/superset_config.py](https://github.com/avniproject/avni-infra/blob/master/reportingSystem/superset/assets/superset_config.py) file && change the database to postgres with flag **SQLALCHEMY_DATABASE_URI**
+
+3. restart the docker it will create metadata in postgres database. here we don't do superset init becuase it creates it's own record which cause issue in primary key
+```shell
+docker exec -it  -u root superset_2.0.1 bash
+superset db upgrade
+```
+
+4. change source & destination in [/assets/pgloaderdataonly.conf](https://github.com/avniproject/avni-infra/blob/master/reportingSystem/superset/assets/pgloaderdataonly.conf) tunnel the postgres db and transfer the data.
+```shell
+ssh -o ConnectTimeout=30 -N  -L 5433:prereleasedb.avniproject.org:5432 ubuntu@ssh.prerelease.avniproject.org -i ~/.ssh/openchs-infra.pem
+## go to second windoow
+pgloader pgloaderdataonly.conf > db_transfer.txt
+```
+
+5. now check the db_transfer.txt and if error then try to resolve and don't move ahead
+
+
+6. reset the sequence [/assets/reset_sequence.sql](https://github.com/avniproject/avni-infra/blob/master/reportingSystem/superset/assets/reset_sequence.sql) .so, we don't get error for further update. if sequence not used and give error ignore that.
+   
+
+7. go to container and run db commands. if any error then try to resolve here. don't move further
+```shell
+docker exec -it  -u root superset_2.0.1 bash
+superset db upgrade
+superset db init
+```
+
+---
+### Upgrate to superset docker 4.0.1
+
+
+1. stop the superset_2.0.1. copy data from  [/assets/superset_config.py](https://github.com/avniproject/avni-infra/blob/master/reportingSystem/superset/assets/superset_config.py) and add require flags and configuration
+```shell
+docker stop superset_2.0.1
+#check /home/ubuntu/supersetdata exist or not if not then create
+cd /home/ubuntu/supersetdata
+vi superset_config.py
+```
+
+2. get logo of avni
+```shell
+cd /home/ubuntu/supersetdata
+wget https://avniproject.org/static/avni-logo-color-b42a730b01c55efe37722027d9cddd95.png
+mv avni-logo-color-b42a730b01c55efe37722027d9cddd95.png avni.png
+```
+
+3. run docker for 4.0.1
+```shell
+docker run -d -p 8088:8088 \
+  --network superset_network \
+  --name superset_4.0.1 \
+  -e SUPERSET_CONFIG_PATH=/app/superset_config.py \
+  -v /home/ubuntu/supersetdata/superset_config.py:/app/superset_config.py \
+  -v /home/ubuntu/supersetdata/avni.png:/app/superset/static/assets/images/avni.png \
+  apache/superset:4.0.1
+docker logs -f superset_4.0.1  
+```
+
+4. important commands for docker container
+```shell
+docker logs -f superset_4.0.1
+docker exec -it  -u root superset_4.0.1 bash
+docker start superset_4.0.1
+docker stop superset_4.0.1
+docker restart superset_4.0.1
+```
+
