Hi,

I am trying to migrate data from PostgreSQL to YugabyteDB.  
So i extracted DDL script of a database from PostgreSQL. Created new database and ran \i /home/DDL.script. However, i am getting the below error.

please advise if there is any other alternate approach of data migration from PostgreSQL 9.5 or 11.5 to YugabyteDB

Hi @janani_in

What version are you using ?

Can you retry the script ? The error "[Catalog Version Mismatch: A DDL occurred while processing this query. Try Again"](https://github.com/yugabyte/yugabyte-db/issues/3350) happens when another query happens while the database is running the DDL, and you can safely retry the DDL.

Can you also post a screenshot of `http://<yb-master-ip>:7000/tablet-servers` ?
