Hi all,

We are planning to upgrade from 16.03.03 to 16.09.01 (windows env). We would 
like to know if the upgrade scripts are run at the re-start of tomcat server 
and will the data structure changes be applied to all tenant databases? Suppose 
we have 5 tenants using the same application server but a different database 
server for their tenant databases. We understand the application will be 
upgraded with new war files but would like to know -

1) whether the data structure (dll statements) changes will be applied to all 
tenants also

2) how to find out which release has database changes and which not. This way, 
we can pay attention to which release has structure changes and also verify 
them after the upgrade.

For instance: We see that 16.08.01 has a feature for capturing client address 
and we assume it will have some database structure changes.

If you could provide us advise or directions on how the upgrade generally work 
in multi-tenant environment and how we can verify the changes, we would 
appreciate it.

Thank you,
Thynn
