Planning to migrate from apache ignite 2.7.0 to apache ignite 2.10.0.
Is there any guide/blog/way to migrate without losing any data?
Appreciate your help.

Is it a persistent cluster? If you don't have in-mem regions, then I suppose you should be able to just deactivate the old cluster, update the jars and start a new version – Alexandr Shapkin Aug 20 '21 at 12:56

In the case of an in-memory try to load your data to an external source. The easiest way is to load data into CSV files and after upgrade load data from CSV into the cluster. – Andrei Aleksandrov Aug 24 '21 at 11:56
