During the import of the zeebe records to Optimize, it can happen that some of them have not been migrated properly. That would mean that the tenantId for Process Definitions, Process Instaces, Incidents & FlowNode Instances is still null and not <default>.

For that purpose, there has to be an additional check happening when importing the records to see whether the tenantID is still null. In case thats true and the version of Zeebe is 8.3 or higher, the tenant has to manually be replaced with <default>.

ATs:

• The import of zeebe records checks whether the imported documents have a tenant or not
• The tenant gets replaced to <default> in case the version of zeebe is 8.3 or higher and the tenant is missing
