Time guidelines and migration performance values

Your best estimate of time and space requirements are generated by running EDMT against a
copy of your production database, on hardware (see Appendix D) similar to your production
environment, in a lab environment. For customers who do not have the facility, the following
subsections provide information gathered while performance testing in the labs (see Appendix
E) at Cisco Systems, Inc.

Typical database migration performance values

The following table provides high level guidelines for the upgrade times for Loggers and HDSs
based on the hardware (as defined in the
