Description
How to upgrade an AppAssure Core to 5.4.3.106 and apply the latest update patch without having to go through a core service restart and a repository check between the two applications.
The latest update patch can be downloaded directly from the AppAssure Support Portal using this link

Resolution
Please note that the update MUST be installed after upgrading the Core to build 5.4.3.106.
The solution for a smooth upgrade is to keep the core service disabled at all times, both during the upgrade and the install of the update.
NOTE: Upgrading to the 5.4.3.106 Core build removes the core service and reinstalls it. Afterwards the installer attempts to start the core. Therefore, just disabling the core service for the duration of the maintenance operation is not enough.
You can achieve the goal of keeping the core service stopped at all times, by entering a command in an elevated powershell console. The result is that the core service will be forcebly disabled every 2 seconds for the duration of the execution on a continous loop. For the period where the core service does not exist during the the upgrade process, the operation will be just skipped.
Although the installer performs all necessary operations that need to be performed before the upgrade, it is good practice to perform them manually before starting the installer so, if something goes wrong, you can pinpoint the issue and take corrective actions without risking a failed upgrade.Please note that all the following Powershell commands are performed at an elevated Powershell Console:
* Suspend snapshots, replication (if present) and VM exports (if present). To do this from an elevated powershell console, please run:import-module appassure* #for Powershell 2.0 only; Powershell 3.0 executes this commandlet automaticallysuspend-snapshot -allsuspend-vmexport -allsuspend-replication -incoming#repeat for all source cores suspend-replication -outgoing
#repeat for all target cores * Make sure that no active jobs are present on the core; wait for the current jobs to complete or cancel them manually. Please note that it is NOT good practice to cancel running Rollups.
get-activejobs -all(The result shows if any active jobs are running)
* Run the following powershell command in an elevated powershell console to keep the core service disabled for the duration of the update operation:
for(;;){start-sleep 2; set-service appassurecore -startuptype disabled -ErrorAction SilentlyContinue; write-host "*" -NoNewline}
Note: This command will run continously, showing a "*" for each iteration.
* Stop the core service. To do this from an elevated powershell console, please run:stop-service appassurecore
Wait for the core service to stop gracefully.* Perform the upgrade by running the newer 5.4.3.106 Core installer. (Please make sure that the installation file is unblocked in the General tab of the properties of the installer.)
* Run the latest update installer specific to the 5.4.3.106 build. (Please make sure that the update installer file is unblocked in the General tab of the properties of the installer, although unlikely, it may be necessary to run it in compatibility mode)NOTE: In this case the latest update is P-001368* It does not matter if you leave checked the "restart service" check box as the core service is disabled via PowerShell.
* Return to the PowerShell window and stop the PowerShell operation that keeps the Core service disabled by hitting CTRL-c.* Enable the Core service. To do this from an elevated PowerShell console, please run:
sc.exe config appassurecore start= delayed-autoNote: There is a space between "=" and "delayed-auto"
*Start the Core service.To do this from an elevated PowerShell console, please run:start-service appassurecore* Wait for the core service to start and for the repository check to complete.
* Resume snapshots, replication (if present) and VM exports (if present). To do this from an elevated powershell console, please run:
import-module appassure* #for Powershell 2.0 only; Powershell 3.0 executes this commandlet automaticallyresume-snapshot -allresume-vmexport -allresume-replication -incoming#repeat for all source cores resume-replication -outgoing#repeat for all target cores resume-snapshot -allresume-vmexport -all* The upgrade operation is completed.
