How to Install a Specific UISP Version
Use this guide if you want to try out the beta version of UISP.
Use installation script argument --version <version> to install a specific UISP version other than the latest official release. This is for testing purposes only. Downgrading to an earlier version will almost surely corrupt your existing data especially if the CRM module is enabled. In case it is necessary to downgrade, we strongly suggest to uninstall UISP, perform a clean install of the lower version, and apply the backup from that version. Upgrading to a newer -rc or -dev version, before it is officially released, can cause errors that will prevent further upgrades.
Use the --update flag to preserve existing UISP configuration without having to specify all the installation arguments again.
curl -fsSL https://unms.com/v1/install > /tmp/unms_inst.sh && sudo bash /tmp/unms_inst.sh --version 1.1.0-beta.3 --update
