Were there any changes in this area with SQL Server 2014? I’ve seen this post Is it possible to restore Sql Server 2008 backup in sql server 2005 and I know that this was no
No, it is not possible. Stack Overflow wants me to answer with a longer answer, so I will say no again.
Documentation: https://docs.microsoft.com/en-us/sql/t-sql/statements/backup-transact-sql#compatibility
Backups that are created by more recent version of SQL Server cannot be restored in earlier versions of SQL Server.
