Write data into aerospike when the migration is not complete?

Is there any problem to write data to aerospike cluster when the migration is not completed ? I know, if I read data from aerospike when the migration is not completed, the result maybe inconsistent, so I suppose at that time, if I update some record, the behavior will be not stable and out of control. If I only write data ( not update), is it okay or have some potential issue?

Use Version 3.13+ - much superior migration performance overall.
