- If I upgrade to Continuity Engine 2021, will my perpetual license cease? Yes, you are accepting SaaS license. requirements outlined in the new EULA for Term and Rental. Neverfail will generate new license authorizations for your current deployment. This means you will need to pay for support to continue software operations yearly or monthly depending on the type of license. Please read carefully the Continuity Engine Licensing Model article.
- Can I upgrade using the Upgrade Wizard from 6.7 to Continuity Engine 2021? Yes, the upgrade wizard is still supported. Keep in mind that Continuity Engine 6.7 and 7.0 are currently End-of-Life (EOL). To ensure organization continued support, we would encourage you to upgrade to the latest version.

Neverfail Engine Plug-ins
Note: Detailed information about each plug-in is contained in the plug-in's knowledgebase file that is available by clicking on the link.
Neverfail plug-ins provide protection for specific installed application configuration data, services, and application data files.
The following plug-ins are included in this release of Neverfail Continuity Engine and are installed automatically if the application is present:
Initial installations of Neverfail Continuity Engine Plug-ins must be performed using the Engine Management Service. Subsequent plug-in re-installations and upgrades may be performed using the Applications: Plug-ins tab of the Neverfail Advanced Client. However, Neverfail recommends that any subsequent plug-in repair installations or upgrades to be performed using Engine Management Service.
To manually install a Neverfail Continuity Engine Plugin follow the How to install a Neverfail Continuity Engine Plugin using Advanced Management Client procedure.
- Passwords starting and/or ending with space ( ) character(s) are not supported (EN-3935).
- (Re)cloning limitation: Disconnected Engine cluster after a cloning or recloning action: recloned node is connected to wrong port group. Workaround documented in Neverfail Continuity Engine Cloning and Recloning limitations: disconnected Engine cluster (EN-3354)
- Recloning limitations when Neverfail Engine passive nodes when static routes are configured: these are listed in Neverfail Continuity Engine Recloning limitations when static routes are configured (EN-3355)
- Neverfail Engine Localization limitations: following localized versions of Windows Server targets/topologies are supported for Engine installation: (EN-3221)
- any WS2008R2, WS2012/R2, WS2016 OS domain or workgroup member protected by HA, DR or HA+DR Engine topology having only alphanumeric chars in its hostname and AD domain name
- any WS2008R2, WS2012/R2, WS2016 OS domain or workgroup member protected by HA or DR-with-same-Public-IP Engine topology having only alphanumeric chars in the AD domain name
- Engine Management Service will not uninstall a server with an expired license (EN-1315).
- Affects only vCenter Server 6.x protected by Engine v8.x (or newer) DR deployments with the DR-node configured with different IP address: Managed ESXi hosts appear as disconnected in vCenter Server/vSphere Client after making DR node active. (EN-2042).
- The Neverfail Continuity Engine .msi installer package is sometimes detected as having untrusted publishers (EN-969).
- The FileServer plug-in bundled with Neverfail Continuity Engine v8.5 (or newer) properly replicates DFS namespaces. The DFS Management Client does not load the namespaces correctly each time.
- Affects only MOVEit Central/Automation Server protected by Engine v8.5 (or newer): Local folders specified as source/destination in MOVEit Automation tasks require user-defined filters for protection. (EN-2879)
- Affects only Engine clusters upgraded from Ipswitch Failover 9.0/9.5 to Engine 8.5 (or newer) (when Create and maintain shadows automatically was not enabled): Progress Failover shadows are still visible as restore points in DRM after upgrading to Engine 8.5 (EN-2863)
- Affects only upgrades from Ipswitch Failover 9.0/9.5 to Engine 8.5 (or newer): Some Ipswitch Failover 9.0/9.5 log and configuration files are not deleted when upgrading to Engine 8.5 (EN-2820, EN-2861)
- [Applies to 8.5 (or newer) with Cozen Identity configured] vCenter Inventory passive VMs are not detected as Protected nodes if management name is configured and webservices are stopped on the active. Dashboard's protected servers count in Global Inventory is also impacted. (EN-4647)
- conditions: Cozen name configured AND active server webservices stopped
- result: deployment.location is not available hence the clustername mechanism is used. that makes only the Active server to be reported as protected node (if VM). Passives cannot be determined as vmid is not available
- [CE9.0 HTML5 UI] When extending from pair to trio (add DR to HA pair) Secondary webservices require restart in order to serve (when made active) the updated deployment topology (trio instead of pair). This is known as the webservices are not restarted on S and S is the T's cloning source. (EN-4657)
- impact: only if S is made active before webservices restart: new HTML UI Datacenter info is not accurate on Tertiary. Possible Protected node count is wrong if cozen identity is configured on any of the passives.
- remediation: restart webservices on Secondary/Tertiary
- [AMFx]: User defined sponsor is not persisted in prefs till Engine service is restarted. Thus webservices don't know about it (till restart is done) (EN-4341)
- [CE9.0 HTML5 UI] Active compression type is shown as 'Standard' when there are no passive instances present in the replication chain. Workaround: This issue is purely cosmetic and it will correct itself once there are passive instances present in the replication chain. (EN-4855)
- [CE9.0 HTML5 UI] Data traffic value in serverlist API is not always accurate. (EN-4859)
- [CE9.0 HTML5 UI] Reconstruct pair: transform from pair HA to pair DR> HA cached configuration must be cleaned up before defining new DR config (EN-4915)
- [CE9.0 HTML5 UI] Startup Engine service may experience delay when unreachable nodes are selected for starting the service on. (EN-4949)
- [CE9.0 HTML5 UI] EULA accept is required all the time when Engine service is stopped (even if previously accepted). (EN-4958
- [Websvc]: Shadows> Configure shadows POST has no effect when "isEnabled":false. Consequence: you cannot configure shadow location when automatic shadow is disabled. (EN-4832)
- [Rollback manager]: Invalid path configured by default for shadow location: C:\PROGRAM FILES\NEVERFAIL\\R2\SHADOW\ (EN-4834)
- [EMS UI]: Internet explorer shows old Client version after upgrade. (EN-3223)
- [EMS-UI] - Add file filters: autocomplete patterns not working for sub-folders if root folder string contains unicode chars. (EN-3246)
- Latched Rules should be displayed in the EMS UI with only one "On Failure Action" drop-down field (EN-2023).
- Downloading the Advanced Client from EMS silently fails in Chrome (EN-1836).
- Neverfail Continuity Engine does not allow a user to create a VM (Secondary) server when only a Primary and Tertiary server are present (EN-508).
- If the targets for network monitoring are not configured, the network status shows -1 missed pings (EN-704).
- EMS> Uninstall Engine wizard hangs at "Initial checks succeeded. Performing further validation..". Cause: A Subsequent uninstallation attempt is made from EMS after a previous failed uninstallation wasn't acknowledged (by clicking OK...) from the EMS> Status. Workaround: Restart Neverfail Engine Management Web Services on the EMS Server then login again to Engine Management Services console. (EN-3859)
Engine Management Service
- With SQL Plug-in + SQL 2014 & In-Memory Tables may result in an OFFLINE DB state during "In Recovery" state (EN-329).

Workaround: Restart Neverfail Web Services on the active server. (EN-1354)
- Virtual Bytes rule triggered at every check (EN-859).
- The Engine Management Service MSI repair mode fails to operate properly (EN-1389).
