I'm new to Sharepoint and need to optimize the powershell script for auto-installing the solution in Sharepoint server. Currently the pre-written script does following:

  • Uninstall-SPSolution
  • Remove-SPSolution
  • Install-SPSolution

For each of these operations, it waits to stop timer job also. Will it make any issue if I replace all there using Update-SPSolution call? Will it update the xml and resource files with this call?

In this scenario you have to be clear about ,

  1. If the solution contains the same set of files and features , that is no new features or files been added in the existing Installed solution then you can use

    Update-SPSolution command

    2.If any new files been added or features been in the existing installed solution then you you need to foloow below steps:

Uninstall-SPSolution and Install-SPSolution cmdlets, respectively

  • Just to confirm, Remove-SPSolution will also be required?

You have to add ReplaceContent = "TRUE" to each resource file It will replace with updated file using Update-SPSolution

  • I found in Sharepoint logs that OWSTimer.exe resets the Aplication Pool when a solution is deployed, will it stop the application pool to get recycled?
