In the rest of this procedure, DATA_DIR denotes the location of the FM Data directory.

## Notes and limitations¶

For each version of FM, we publish Release notes, which indicate the detailed limitations, attention points and notes about release. We strongly advise that you read all release notes for the new FM version before starting the upgrade.

Warning

Before upgrading, it is very highly recommended to backup the whole content of the data directory.

Stop the old version

DATA_DIR/bin/fm stop


Unpack the distribution tarball in the location you have chosen for the new installation directory.

cd SOMEDIR
tar xzf /PATH/TO/dataiku-fm-NEWVERSION.tar.gz
# This creates installation directory SOMEDIR/dataiku-fm-NEWVERSION for the new version


dataiku-fm-NEWVERSION/installer.sh -d DATA_DIR -u

DATA_DIR/bin/fm start
