After 15yrs to 20yrs of worth data/usage/history and know there was issue with security list (because of "Unidentified Security" - tied to a corrupt security list I believe), I'm in process of setting up and transferring data (MASSIVE JOB) into a new quicken clean file.
On my new clean file, what is the best method to avoid future issues on holding same security at two or more brokerages?
It seems from what I'm seeing is that I can get different cusip #s depending upon the brokerage, thus probably should have it add new security when this happens?
If I combine under one cusip from a broker and combined all same security symbols under one cusip (downloaded from brokerage) then if I no longer have it from the original created brokerage or security at that brokerage, then maybe it won't update properly on the same security held at other brokerages (history), etc.
Please provide your thoughts, I want to make sure I'm on the right path and wish to avoid future issues.
Thanks in Advance!!
