Comptoir Isser: the test bench before replacing old software

An invented Boumerdès wholesaler, twenty years on software its publisher abandoned, and the bench we run before pricing its replacement.

Try it yourself

Opening of the Comptoir Isser migration bench with the old software’s name and three figures: years of data, rows read, names lost.
01The starting pointTwenty years of data, hundreds of thousands of rows read and names lost: the situation is set out before any recommendation.

Comptoir Isser

Twenty years on software with no vendor, and the bench we run before quoting.

Open the demonstration (opens in a new tab)

Two of the four modules come back “keep it”. That is half the requests we get on this subject, and it is what the bench exists to say.

Comptoir Isser is a Boumerdès wholesaler that does not exist, and neither do its old software or its data. We invented it to show what a business that has run for twenty years on a program with no publisher can have before replacing everything: a reasoned decision, module by module, and proof that its data can come out.

The screenshots below come from the demonstration itself and are retaken automatically after every change. No real database is read: the records, the discrepancies and the names are made up, and no system stops when you touch the cutover button.

Trying it in a few minutes

  1. Read the verdict

    Go through the grid of four modules and open the two that stay on the old software to read why.

  2. Open a damaged name

    In the encoding survey, press see on a recoverable name, then on a lost one, and compare the two answers.

  3. Settle the discrepancies

    Replay the extraction, then choose for each discrepancy in the parallel run which system is right.

  4. Try the cutover

    Name the missing arbiter, produce the archive and watch the button unlock.

Frequently asked questions

Is Comptoir Isser a real business?

No. The wholesaler, its software, its clients and its figures are invented. Boumerdès and the Isser river are real, and the problems shown are the ones we meet on this kind of project.

Is my data read or sent anywhere?

No. The demonstration connects to no database and receives no file. Everything it shows is made up, and the cutover button stops nothing.

Why does the bench advise keeping two modules?

Because old software that does its job, with no exposure and no lost data, costs less to keep than to replace. Saying so before pricing is part of the work.

Can my business go through the same bench?

Yes, on its own system: its modules, its tables and its real discrepancies. We do not sell this demonstration; we carry out this work on your software.

How to start

Open the demonstration and follow the four acts, from the verdict to the cutover: ten minutes is enough to see how a migration is decided and proved.

If your business depends on software nobody maintains any more, write to us: we look together at what should be migrated, and what is better kept.
