anchor.diff:  Note that there is also a `--account-export=<account_id>` flag to export the data associated with a specific Kill Bill `account_id`.
   
   
  -In order to get information about your Kaui server installation, the following command can be used:
  -
  -```
  -# Login as 'tomcat'
  -> sudo su - tomcat
  -#
  -# Assume a 'bob/lazar' tenant
  -# Assume some credentials 'admin/password'
  -# Details about DB host and killbill-url can be extracted from '/var/lib/tomcat/bin/setenv2.sh'
  -# 
  -kpm  diagnostic \
  -  --killbill-credentials=admin password \
  -  --bundles-dir=/var/lib/killbill/bundles \
  -  --database-name=killbill \
  -  --database-credentials=killbill killbill \
  -  --killbill-api-credentials=bob lazar \
  -  --kaui-web-path=/var/lib/tomcat/webapps \

   == Upgrade Steps
   
   === Newer AMIs
  
positive.code: The Kill Bill core team will provide new AMIs whenever necessary.
  
  Because the CloudFormation from AWS Marketplace will always reflect the latest AMI ids, you can simply update the stack with the latest CloudFormation template and the instances in the AutoScaling groups will be updated automatically.
  We strongly recommend to always test the upgrade in a test environment first.
  
  We recommend to rely on the CloudFormation `ChangeSet` functionality to get a sense of what would be updated if the change was submitted. For more information about the CloudFormation `ChangeSet` functionality see this https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks.html[documentation]. Below is a summary of the steps:
  
  [1]. Update your CloudFormation template with the new Kill Bill and/or KAUI AMIs
  
  
negative.code: > service kaui restart
  ```
  
  === Access to the Database
  
  From any Kill Bill EC2 instance, it is possible to access the RDS database. On each node, there is a `mysql` client installed
  allowing database access. The database hostname can be obtained from the CFN Resources screen, or one can also
  extract this information from the `killbill.properties` file:
  
  ```
  > grep 'org.killbill.dao' /var/lib/killbill/config/killbill.properties
