How can you transfer the CDE Database from a 200light to a 200EL Mitel PBX?

Mitel used to do this, but no longer since it is discontinued and a few generations back. The ICP will convert a EL database.

I recommend a re-key. It doesn't take that long to retype a Mitel database. In fact, form 26* is probably the longest part.

Print the db from the Digital Light, and then just re-type it. You can also dump the db through a terminal emulation program, with "capture file" turned on, and save it as a text file on your laptop. Then use that as a guide while you re-key.

I agree with the rekey :), I think putting buttons on phones will be longer than 26. Either way, you can correct things that aren't right, or can be done better.

Thanks, fyi this 200light has 18 working COS... Work is work...so I am not complaining.
Thanks, again

Thanks John, I appreciate your response as well.
