+= Version Upgrade
+
+Upgrade is an important part of the lifecycle of any software system. This
page covers the basic recommendations for upgrading the Apache Ignite version.
+
+== Upgrading Nodes
+
+Updating node version is as simple as replacing the Apache Ignite binaries
with a new version. However, there are several things to keep in mind when
performing the upgrade:
+
+- Ignite cluster cannot have nodes that run on different Ignite versions. You
need to stop the cluster and start it again on the new Ignite version.
+- It is possible to accidentally overwrite your persistent storage or other
important data during the upgrade. It is recommended to move this data outside
of intallation folder if you are planning upgrades:
+* The work directory is used to store application data and all data required
for the node to work. You can change its location as described in tge
link:setup#configuring-work-directory[Configuring Work Directory] section.
+* The persistent storage holds all information stored on the node. You can
change its location as described in the
link:persistence/native-persistence#configuring-persistent-storage-directory[Configuring
Persistent Storage Directory] section.
+* WAL Archive os used to store WAL segments for recovery. You can change its
location as described in link:persistence/native-persistence#wal-archive[WAL
Archive] section.
