Already did this! the build.properties has:
IIQVersion=8.4
IIQPatchLevel=
acceleratorPackVersion=8.3
the base/ga folder has identityiq-8.4.zip and base/patch has identityiq-8.4p1.jar, and base/ap has Accelerator_Pack-8.3.zip
When I tried to build it up, it failed with the message of "System version 8.3-45 does not match database version 8.4-104”
