Due to a compatibility issue, we strongly recommend to upgrade EN's binary to v0.9.6 if you have been running an EN with older versions (<= v0.8.2). If it is your first time upgrading the EN to v0.9.x and want to migrate the data from the older version, you must specify the option ADDITIONAL="--db.num-statetrie-partitions 1" in the configuration file when you install the newer version.
