A departure rehearsal, in your accounts.

Your administrator sets up read-only access, then one command runs everything. You do not leave your provider, and you have nothing to request from them.

Everything happens in your accounts: your data platform, and the host you choose

Set upA small open warehouse is created at the host you chose: one machine, one storage bucket, one catalog of Iceberg tables.
CopyYour data is read with no ability to modify it, then written in Iceberg format to another of your accounts.
ReplayThe 20 most important queries, chosen with you, run on both sides.
CompareTables and results are compared with tolerances written in advance: row counts and per-column statistics are recomputed in the source engine, and a content fingerprint compares the rows as Canot read them with the copy.
SignAn evidence file is produced: parity, duration, cost, and what does not move as is.

Canot sends nothing to Q4O: no telemetry, no server.

canot scanFree read-only X-ray: volumes, objects that do not move on their own, estimated exit duration and cost.
canot drillThe full drill and the evidence file.
canot teardownDeletes what was copied.
