Dear Paul,

> AFter more than a decade of service we will be retiring our Channel Archiver and begin using the Archiver Appliance.  Is there a tool to migrate/move data out of the Channel Archiver and put it into the data stores of the Archiver Appliance?

Yes, there are at least two, arget (part of carchivetools) and ca2aa.
You can find both of them in github:

https://github.com/epicsdeb/carchivetools
https://github.com/mdavidsaver/ca2aa

cf. https://indico.fnal.gov/event/9718/contributions/115209/attachments/74704/

We used arget to convert our 10-years of Channel Archiver data to AA
in 2017. I tested both and found that ca2aa works much faster but
arget is suitable for our site because it retrieves a PV stored in
multiple keys.

Best regards,
Shuei
