We've been running DDMi 9.32 and uCMDB 10.11 in large environment (30K servers). Both applications are used to populate AM via CIT - with DDMi providing inventory scans and the CMDB host/guest relationships via discovery patterns - no scan data.
We are targeting migrating DDMi to uCMDB next month. The migration guide outlines how to move from DDMi to CMDB .
My quesiton is this: I'd like to flush the CIs out of the existing CMDB before cutting over, since there are differences in how the discovery patterns populate information and how scanner discovery captures the data.
What's the best method (read least risky) to clear / flush the CMDB so that all discovery data can be reset to scans?
We are trying to keep the AM data consistant and think this would be the least painful mehod to cut over.
