How to calculate efforts (hours) required for upgrading maximo

This is a vast topic but I will give a basic summary required : -


1. Note down all customizations (Custom Classes and automation scripts).
2. Note down all test cases done for core maximo implementation (critical one's )
3. Note down all integration/dependent addons/reporting/Unix scripts involved.
4. Divide no. of hours based on hour's per individual.
5. Make an excel to with gantt chart similar to Maximo Schedule for resource allocation.
6. Check all latest features you can use from new Maximo or check what existing customization can be removed after upgrade.
7. Add certain number of hours for customization which you might need to do because of incompatibility with existing customization/code optimization/ java code to script conversion.
8. Add time required to run each test case.
9. Note down all assumptions, dependencies, and Risk.
10. Add time required for weekly status meetings.

Integration Control

Integration control used in making conditions for processing  provides a way to match xml field or object field with particular value. We have 4 types of integration control 1. Value 2.List 3. XRef 4.Boolean Value control is used to compare with single value. List control is used to compare with list of values which may come from domains. Boolean control is true or false value used to compare yorn field I personally never used it. XRef control i.e cross reference control is used to to swap values foe example we have different orgid in other system than we can define cross reference control inorder to translate. We create cross reference control and associate it with enterprise service or publish channel. We can also override these values at external system level.
