Did you rename the backup file?

I’m not sure about renaming. Maybe. Does it affects?

Yes, it stops the restore from working. That’s why you’re seeing the following error message.

EXCEPTION: Migration version is missing from the filename.

Can you rename it back to the original filename?

I don’t know the original filename. Also, I don’t have access to old server. I’ve the .gz backup file only.

Any way to find the filename or any other way resolve this??

Thank you.

Open the backup file and extract the dump.sql file from the dump.sql.gz. Open the dump.sql file and look for a block of numbers that gets inserted into the schema_migrations table.

COPY public.schema_migrations (version) FROM stdin;
20000225050318
20120311163914
20120311164326
...
20181031165343
20181112013117
20181120140552
\.

Take the highest number and append it to your backup file. Make sure to prefix the number with -v. For example, it might look like this: mybackup-v20181120140552.tar.gz
