Hi,
How easy is it to migrate from Cognos Express to the Full Cognos BI? Does everything just upgrades automatically or do you have to rebuild all the framework model and reports?
Deployments from Express will restore straight into Cognos Enterprise BI - you do not need to recreate any FM models or reports. The only issues you might face are if you used Express users rather than Active Directory users - if so you will need to set up these users in a supported Enterprise authentication provider and define their roles etc.
Regards,
MF.
