Migration from U8.2 to U9.4

Author: spanish_uniface@hotmail.es (uniface8)

Hi all, i have a question, is really necessary to migrate first from 8.2 to 8.4 before to 9.4? or can we do it directly (from 8.2 to 9.4) ?



  1. Yes, it is necessary to  migrate first to 8.4 before you can migrate tot 9.4. The Uniface Guide tells you how to do that. Migrate is a big word. You only have to export your repository from 8.2, import it in 8.4, compile etc. your application, export it from 8.4 and than import it in 9.4 That's all.

  2. Hi Rafa,

    because it's a runonce issue all you need is a 8.4 installation CD or ZIP (and a valid uniface license).

    Just install uniface using SOLID as the database (their evaluation license is enough for our purposes).
    We will work in the project directory created during the installation.

    Export all your reporitory (except DICT, PRINTER, SYSENV, ...) from 8.2.

    Start the 8.4 database service

    Start the 8.4 development
    Import the 8.2 file
    Export all so we have our 8.4 stamped export file

    Store this file in a secure place

    Stop the 8.4 database service

    And it's "Time To Say GoodBye" to the 8.4 installation.

    SUccess, Uli

  3. ... but if you have a good relationship to your local CPWR contact, they may come with a PC to your location and do that 10 min excercise for you (free of charge).

  4. Thank you for your advices.
    I´ll import to 8.4 first and then we´ll do the migration to 9.4.

    Regards, Rafa.
