• The values in the Database Used Size in the table above are based on the amount of disk

space used by the Source database, not the size of the disk it resides on.

• For Technology Refresh upgrades, have the fastest network possible (gigabit through one

network switch) between the source and the destination machines. Use of a crossover cable
is not supported because it lacks buffer memory and can cause data loss.

Run timings, Technology Refresh and Common Ground

The conversion should take place in less than a half hour—in most cases, much less. The actual
time can vary based on the parameters discussed in the

Performance considerations

During internal testing, hyper-threading has consistently doubled the time it took the database
migration to complete; therefore, to minimize migration time you should disable hyper-threading.

Ways to reduce data migration time

You can reduce data migration time with the following methods.

•

Reduce database size:

–

Purge the Logger DB of all data already replicated to the HDS (25 GB or less)

–

Remove redundant records, especially RCD, RCV, TCD, and TCV tables via ICM Purge
Utility and/or SQL Query Analyzer
