Incremental upgrade via Unload/load (XOB) (continued…)
Upgrade approaches
Pros
•Allows you to continue developing – minimal business impact.
t.
•Applications are upgraded as the need arises.
Cons
•Same application exists in multiple databases, preferred approach is to delete from the original database.
•Need very strict controls when using this method to ensure existing objects are not overwritten. Recommend 
backing up the destination design database prior to each load.
•Extra testing needs to be carried out with each load into the destination design database.
When to use this approach
•When business as actual activities in the current version need to continue.
•If you want to merge applications from multiple databases into 1 database.

Upgrade approaches
Cons
•Requires extra controls to manage multiple versions of the engine running in production.
.
•Difficult to make urgent changes to an application that hasn’t yet been upgraded.
.
When to use this approach
•If business as usual activities need to continue.
•If you have many applications that don’t change regularly or applications that change on a predetermined 
basis – for example, once a year or once a quarter.
.
As an example: You have 50 applications in the database. 30 change regularly and 20 don’t. You could test 
the 30 applications and upgrade them but leave the remaining 20 until time permits or just leave them 
running in the existing version.
