Frequently Asked Questions


- Beta Subscription and Registration Code
Warning: Beta Registration Code

Registration is not working with your regular SLE Micro key, special Beta Registration Code is required. Thus, you don't have access to the SLE online channels/repositories and Modules without a Beta Registration Code. The Beta Registration Code is the key to unlock the Beta Subscription in our SUSE Customer Center. The Beta Subscription consist of giving access to our SLE Micro Beta Online Channels. We will not provide a beta product subscription or beta product registration code by default for the SLE Micro Beta Program. You might request one via, please specify if you want a registration code for which architectures.  

- Migrating from SLE Micro 5.3 to SLE Micro 5.4 Beta

Update from SLE Micro 5.3 to 5.4 is now supported. Unlike with SLES, which offers several methods, with SLE Micro there is only one method available, via transactional-update.

- Updating from SLE Micro 5.4 Beta to the next SLE Micro 5.4 Beta

Even if it's completely feasible and working, we do not recommend to update from "SLE Micro 5.4 Beta X" to "SLE Micro 5.4 Beta X+N" for your thorough beta testing. Why? Because this scenario is specific to beta and can not be compared to any SLE Micro production update scenario. During the beta phase of our products, we need the flexibility of doing important changes to packages (libraries, configuration files, features, etc), like upgrading or downgrading to different versions. Thus changes between SLE Micro Beta might look very different from regular updates we make in official SLE Micro releases. We highly recommend to test the following scenarios, whenever a new Beta version is released:  

- Updating from SLE Micro 5.4 Beta to SLE Micro 5.4 GM
Warning: Migration from Beta to Gold Master

Migrating from SLE Micro 5.4 Beta to SLE Micro 5.4 Gold Master (the final and official version) is NOT SUPPORTED. If you want to put the final version of our product in production, you need to do a fresh installation or a migration from an existing supported version. We will not support the migration from a beta product to a final release of the product. As a reminder, our SUSE Beta EULA states that you should not put SUSE Beta Products in production.
