What happens to data after it crosses retention policy

We are storing vehicle data in our database. I am thinking about a retention policy of 6 months.
After that 6 months, can I migrate this data to some other database, so that it is not deleted in case we need it again.

Will all the data be deleted after 6 months ? I think it will be available in the autogen RP, OR not ?

@Luv This downsampling doc should answer those questions for you.

So, my data will get deleted using RPs. That means migrating the data after 6 months will be a good option then, right ?

@Luv Yup! You could use a CQ to reduce the granularity on the data and move it to an RP with a longer retention period.
