Failure writing points to database: partial write: points beyond retention pol (truncated...)

Hello,

I’m scheduling to run influxdb migration between 2 servers on debian (original physical, destination virtual)…

To run it smoothly, my application will send data in parrell to the 2 databases, if all is working well I will be able to switch off the original one.

To do it, I have restored my db to second server, to get a full identique copie of db and my application is sending data to both influx.

On my second db, I got error message ‘failure writing points to database: partial write: points beyond retention pol (truncated…)’
I have check the row data (in case of) but data are the same

The retention policy of course are the same because full data restore accomplished.

Source influxdb version : 2.7.1
destination influxdb version : 2.7.10

Do you have some ideas why I get this error, today I’m really confused and not able to run my migration.

thanks in advance for your support
