+# Upgrade notes
 
-The wizard is here to help the user in the process of upgrading an existing installation.
+Crowdsec does it best not to break existing setups, and the following rules generally applies :
-Various items need to be kept during the upgrade process:
 
- - scenarios/parsers/postoverflows : upstream scenarios need to be updated, while local/tainted ones need to be kept as-is
+ - patches (`X.X.Y` to `X.X.Z`) can be applied blindly and are for bugfixes and backward compatible changes
- - most configurations must be kept as-is (`acquis.yaml` `*_credentials.yaml` `profiles.yaml` `simulation.yaml` `config.yaml`)
+ - minor (`X.Y.X` to `X.Z.X`) can be applied blindly but might introduce some features that are not backward compatible
- - database (especially if it's a SQLite file)
+ - major (`Y.X.X` to `Z.X.X`) must be applied with caution as they might break existing installation
 
 
+!!! warning
+
+    We **strongly** advise you against running crowdsec and LAPI in different versions.
+    When upgrading existing setup, we suggest you to upgrade both crowdsec, cscli and LAPI.

 ## Patch upgrade
 
 `wizard.sh --binupgrade`
 
 When doing a minor/patch upgrade (ie. `1.0.0` to `1.0.1`), the `--binupgrade` feature should be the more appropriate : It will simply upgrade the existing binaries, letting all configurations untouched.
 
-As any breaking change should lead to a version bump and appropriate warning, this is the safest option.

 ## Minor upgrade
 
-
 `wizard.sh --upgrade`
 
 When doing a minor upgrade (ie. `1.0.4` to `1.1.0`), the `--upgrade` feature should be used : It will attempt to migrate and upgrade any existing configurations, include tainted/custom ones. The ambition is to be able to upgrade scenarios, parsers etc to the latest version when relevant, while keeping custom/tainted ones untouched.

 It's using `cscli config backup`, creating a directory (usually `/tmp/tmp.<random>`) in which it's going to dump all relevant configurations before performing an upgrade :

+[`cscli config`](/Crowdsec/v1/cscli/cscli_config/) is your friend here, with [`backup`](/Crowdsec/v1/cscli/cscli_config_backup/) and [`restore`](/Crowdsec/v1/cscli/cscli_config_backup/) subcommands allowing you to backup and restore all of the configuration files.

+[`cscli hub`](/Crowdsec/v1/cscli/cscli_hub/) allows you to view, update and upgrade configurations :
+
+ - [`cscli hub update`](/Crowdsec/v1/cscli/cscli_hub_update/) downloads the latest list of available scenarios/parsers/etc
+ - [`cscli hub list`](/Crowdsec/v1/cscli/cscli_hub_list/) lists all the installed configurations, their versions and status
