Hello! If you have native persistence configured, you should be able to start 2.10 nodes with 2.7 persistence files. Just restart all of your nodes at once to the new version.
If you have a purely in-memory cluster, it is assumed that you are ready for occasional full cluster restart and starting anew (repopulating data, etc). In this case it may be even possible to bring up the new cluster, switch the load to new cluster, sunset the old one. Apache Ignite does not have support for rolling upgrade yet: it is not possible to bring new version nodes to old version cluster.
