RxDB "Cannot open database state with newer RxDB version" error when trying to update from v13 to v15

[AleksandrMatuka]

Problem:
I'm trying to update my RxDB database from version 13 to version 15, but I'm encountering the next error:

bootstrap.tsx:242 RxError (DM5): RxError (DM5):
Cannot open database state with newer RxDB version. You have to migrate your database state first. See https://rxdb.info/migration-storage.html
Given parameters: {
args:{
"database": "dbname",
"databaseStateVersion": null,
"codeVersion": "15.10.0"
}}

Does this mean that there were changes in version 15 that require us to create a new database with a new name during migration?

If affirmative, it raises concerns. What would be the appropriate approach for updating and safeguarding data from prior versions such as 12/13 to version 15?

Version:
15.10

environment:
chrome

You have to migrate your data, see https://rxdb.info/migration-storage.html
There is no 13->15 migration. You can only migrate one version at a time. In v14 the migration plugin was in the premium package, it was only made open source in v15. If you do not want to get premium access, you can use the json-export/import plugin to migrate.
