I have a co-res CallManager and IPCCE server running CCM version 4.1.3. I'm attempting to upgrade to CCM5.1.1. After I install DMA version 5-0-4 or 5-1-1 I can't access the ccmadmin page. I get prompted for the username and password these are accepted but then I get an "Internal server error" displayed on the web page. Once I uninstall DMA and Informix I can access ccmadmin again. I have tried upgrading the OS to 2000.4.4a(SR6) and CCM to 4.1.3sr4d but this does not resolve the fault. Has anyone seen this before?
