   3. Stop the application

      1. application stop all
      2. application stop vault

2. Backup the Postgresql, and MongoDB databases.
   1. For Jiffy and GUS postgres backups (Commands will prompt for DB password):

      1. pg_dump -h {DB hostname} -p 5432 {jiffy-schema-name} -U {username} | gzip > {filename.gz}
      2. pg_dump -h {DB hostname} -p 5432 {gus-schema-name} -U {username} | gzip > {filename.gz}

   2. For MongoDB backup
      1. Self Hosted
         1. Connect to the MongoDB server.
         2. Switch to the jiffy application user.
         3. Use the following command to prompt the DB admin password.

            mongodump –ssl –host {MongoDB hostname} –port 27017 –sslPEMKeyFile {Keyfile the certificate is a combination of ca+cert} –sslAllowInvalidCertificates –authenticationDatabase admin -u admin –out {filename.dump}

            
            

Pre-Upgrade Steps

1. Connect to the core server.
2. Switch to the jiffy application user.
3. Download the artifact files:
   1. Download helm charts

      1. export JIFFY_INSTALL=“/tmp/jiffy-install/4.9/”
      2. mkdir -p $JIFFY_INSTALL/helm/
      3. cd $JIFFY_INSTALL/helm/
      4. wget –user {username} –ask-password downloads.jiffy.ai/4.9/Upgrade/jiffy-helms-v4.9.zip

      unzip jiffy-helms-v4.9.zip

   3. Download ansible-playbook and upgrade artifact.

      1. cd $JIFFY_INSTALL
      2. wget –user {username} –ask-password downloads.jiffy.ai/4.9/Upgrade/jiffy-playbook.tar.gz

      2. tar -xf jiffy-upgrade.tar.gz -C $JIFFY_INSTALL/upgrade/

4. Fill in the inventory file and variable.yml file as per requirement (use the existing files or parameters from the previous/last installation as reference).
   1. The inventory file will have all the details of the servers, authentication methods, etc.
   2. variable.yml file contains all the parameters such as the username, custom application parameters, mount point, etc.

Backup

Optional for saas environments.

This step will cover code backup, in case of rollback to a previously installed version.

1. Switch to root user in the core server.
2. Activate the ansible python virtual environment Applicable only, if Ansible is installed under python virtual environment

   source /opt/jiffy3rdparty/ansibleEnv/bin/activate

3. Start backup process

   1. export JIFFY_INSTALL=“/tmp/jiffy-install/4.9/”
   2. cd $JIFFY_INSTALL
   3. ansible-playbook pre-upgrade/root.yml -i inventory -e @variable.yml

   For debug mode:

   ansible-playbook pre-upgrade/root.yml -i inventory -e @variable.yml -v

   For detailed debug mode:

   ansible-playbook pre-upgrade/root.yml -i inventory -e @variable.yml -vvvv

4. Change ownership of /tmp/jiffy-install to jiffy application user:

   chown -R {jiffyapp linux user}:{jiffyapp linux user group} /tmp/jiffy-install

5. Switch to the jiffy application user
6. Activate the ansible python virtual environment
7. Applicable only, if ansible is installed under python virtual environment

   source /opt/jiffy3rdparty/ansibleEnv/bin/activate

8. Run the non-root installer : (Sample variable and inventory file below) 1.

   ansible-playbook pre-upgrade/non-root.yml -i inventory -e @variable.yml

   For debug mode:

   1. ansible-playbook pre-upgrade/non-root.yml -i inventory -e @variable.yml -v

      For detailed debug mode:

   2. ansible-playbook pre-upgrade/non-root.yml -i inventory -e @variable.yml -vvvv

      
      

Upgrade Procedure

1. Switch to the jiffy application user
2. Activate the ansible python virtual environment Applicable only, if Ansible is installed under python virtual environment

   source /opt/jiffy3rdparty/ansibleEnv/bin/activate

3. Run the non-root installer : (Sample variable and inventory file below)

   1. export JIFFY_INSTALL=“/tmp/jiffy-install/4.9/”
   2. cd $JIFFY_INSTALL
   3. ansible-playbook pre-req-mail.yml -l core -e @variable.yml

   For debug mode:

   ansible-playbook pre-req-mail.yml -l core -e @variable.yml -v

   For detailed debug mode:

   ansible-playbook pre-req-mail.yml -l core -e @variable.yml -vvvv

   
   

Core Upgrade

1. Switch to root user in the core server
2. Activate the ansible python virtual environment Applicable only, if Ansible is installed under python virtual environment

   source /opt/jiffy3rdparty/ansibleEnv/bin/activate

3. Execute the playbook to begin the upgrade.

   1. export JIFFY_INSTALL=“/tmp/jiffy-install/4.9/”
   2. cd $JIFFY_INSTALL
   3. ansible-playbook upgrade/root.yml -i inventory -l core -e @variable.yml

   For debug mode:

   ansible-playbook upgrade/root.yml -i inventory -l core -e @variable.yml -v

   For detailed debug mode:

   ansible-playbook upgrade/root.yml -i inventory -l core -e @variable.yml -vvvv

4. For sudo and ssh password prompt add -kK options along with run command

   ansible-playbook upgrade/root.yml -i inventory -l core -e @variable.yml -kK

5. Change ownership of /tmp/jiffy-install to jiffy application user

   chown -R {jiffyapp linux user}:{jiffyapp linux user group} /tmp/jiffy-install

6. Switch to the jiffy application user
7. Activate the ansible python virtual environment Applicable only, if Ansible is installed under python virtual environment

   source /opt/jiffy3rdparty/ansibleEnv/bin/activate

   The Crotab of Jiffy application user is updated on each upgrade and therefore all custom cron jobs must be scheduled outside of the Jiffy application user’s crontab file.

8. Run the non-root installer : (Sample variable and inventory file below)

   1. export JIFFY_INSTALL=“/tmp/jiffy-install/4.9/”
   2. cd $JIFFY_INSTALL
   3. ansible-playbook upgrade/non-root.yml -i inventory -l core -e @variable.yml

   For detailed debug mode:

   ansible-playbook upgrade/non-root.yml -i inventory -l core -e @variable.yml -vvvv

9. Execute the below ansible command to update application configuration changes.
   with masterkey prompt:

   ansible-playbook jiffyconfiguration.yml -l core -e @variable.yml

   without masterkey prompt:

   ansible-playbook jiffyconfiguration.yml -l core -e masterKey=’<replaceme>’ -e @variable.yml
