Syndeia 3.4 provides the following migration paths from Syndeia 3.3.
Syndeia Cloud 3.3 → Syndeia Cloud 3.4
If you are using Syndeia 3.3 with Syndeia Cloud, then all of your Syndeia data is persisted on the Syndeia Cloud server. Your Syndeia admin will need to follow the migration process described here - Migration (3.3 -> 3.4).
Syndeia 3.3 Local store → Syndeia 3.4 Local store
If you are using Syndeia 3.3 with a local store, then all your Syndeia data is persisted locally on your machine and SysML models. Follow the process described in 3.3 Local -> 3.4 Local to migrate from Syndeia 3.3 local store to Syndea 3.4 local store. You will have to follow this process for each SysML model you are using with Syndeia 3.3.
Syndeia 3.4 Local store → Syndeia Cloud 3.4
If you start using Syndeia 3.4 with a local store and would like to migrate to Syndeia Cloud 3.4, follow the steps on 3.3 Local -> 3.3 Cloud to migrate your data to Syndeia Cloud 3.4.
If you were using Syndeia 3.3 with a local store and would like to start using Syndeia Cloud with Syndeia 3.4 release, then you need to first migrate from Syndeia 3.3 local store to Syndeia 3.4 local store (see above) before upgrading to Syndeia Cloud 3.4.
