Is it possible to update existing elements to use Unicode encoding?

Hi Dojo,
For a specific connector, a new range was made available to support Unicode encoding as some characters were not displayed and handled correctly with the current version.

Is it possible to enable the Unicode version on all existing elements without recreating them?
The goal would be to keep all linked (function) resources, element connections, element properties, ... .

Thanks in advance

Hi Robin

It is not possible to do this as all existing data will be lost/corrupted as mentioned in the documentation: options attribute | DataMiner Docs

This is why changing to/from unicode is considered a Breaking Change.

EDIT:

It is possible to do this with the requirement that the system needs to use Cassandra for this. A major range is still needed for the protocol to indicate the impact on systems that don't used Cassandra.

Hi Michiel, I believe the values are stored in Cassandra as ASCII and Unicode encoding by default. Should it not be possible to switch since we have the data already?
Why would it still be considered a breaking change?

Hi Robin

After checking internally, this should work, but only on Cassandra databases. MySQL/MSSQL does not support this. The major range for the protocol is still needed to make sure that it is noticed when updating the protocol on a system that does not use Cassandra.
