Upgrade from Maximo V7.1.1.5 to V 7.6

in this post I will illustrate the Upgrade process , in this scenario I have A VM witch have Oracle database 10G Engine ,WAS and finally maximo SMP Folder

1.0 First get some statistics from the system
1.1  the System version 
SMP/Maximo/application/maximo/version.bat
==> its will be maximo 7.1.1.5

1.2 count the important objects like workorder,pr and Prlines ...etc

select count(*) from WORKORDE

select count(*) from PM

select count(*) from PR
select count(*) from PRline
select count(*) from Po
select count(*) from Poline
