Migration from single node to distributed cluster

I am trying to migrate from single orientdb node to distributed cluster. So i've dumped db from single instance

> EXPORT DATABASE /temp/something.export

After I am trying import it in distributed orientdb cluster:

orientdb {db=something}> IMPORT DATABASE /something.export.gz -preserveClusterIDs=true        

Importing database DATABASE /something.export.gz -preserveClusterIDs=true...
Error: com.orientechnologies.orient.core.exception.OStorageException: Error sending import request
    DB name="something"

Error: com.orientechnologies.orient.core.db.tool.ODatabaseExportException: Error on importing database 'something' from file: /tmp/import5802832137826087861something.export.gz

Error: com.orientechnologies.orient.core.exception.OStorageException: Cannot route TX operation against distributed node
    DB name="something"

Error: java.lang.NullPointerException

What I am doing wrong? What does mean Cannot route TX operation against distributed node?

Single instance is on 3.0.34 version and distributed - on 3.2.5.

Start by reviewing the reported EXPORT DATABASE and IMPORT DATABASE commands, the full exception chain, and the version difference between 3.0.34 and 3.2.5. Reproduce the migration if possible and trace the distributed import path around “Cannot route TX operation against distributed node”; done means identifying the cause and documenting a supported migration procedure or required version alignment.
