Hi @sns ,

If all of your KWizCom products are not on the same release version, it is possible for SharePoint to not be able to find a required version of Telerik.Web.UI.dll.

After you deploy the latest version, please check the "OWSTIMER.EXE.CONFIG" file on the server where the SharePoint Timer runs.

1.Go to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\BIN folder

2.Find and open OWSTIMER.EXE.CONFIG file
Note:Please check that you have bindingRedirect for KWizCom Foundation. Make sure that it redirect always to version 13.3.0.0.

<runtime>  
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">  
<dependentAssembly>  
<assemblyIdentity name="KWizCom.SharePoint.WikiPlus.Telerik.Web.UI" publicKeyToken="30fb4ddbec95ff8f" culture="neutral" />  
<bindingRedirect oldVersion="1.0.0.0-20.0.0.00" newVersion="13.3.0.0" />  
</dependentAssembly>  
<dependentAssembly>  
<assemblyIdentity name="KWizCom.SharePoint.WikiPlus.Telerik.Web.UI" publicKeyToken="30fb4ddbec95ff8f" culture="neutral" />  
<bindingRedirect oldVersion="1.0.0.0-20.0.0.00" newVersion="13.3.0.0" />  
</dependentAssembly>  
</assemblyBinding>  
</runtime>  

3.Please make sure that you restart SharePoint Timer (OWSTimer) and restart IIS after you deploy the latest version or make any changes in OWSTIMER.EXE.CONFIG file.

Hi @sns ,

1)Remove Site collection using PowerShell:

• Remove-SPSite cmdlet with -GradualDelete switch

The -GradualDelete parameter instructs to delete the site collection gradually, instead of consuming all system resources to delete the site collection instantly in a single stretch. This reduces the load on the system when deleting large site collections.

Remove-SPSite -Identity "Site-collection-URL" -GradualDelete  

- Force delete SharePoint site collection with PowerShell

If you face any difficulty in deleting SharePoint site collection either from Central Admin or with PowerShell, you can force delete site collection from the content database as:

#Get the site collection to delete  
$Site = Get-SPSite http://site-collection-url  

#Get the content database of the site collection  
$SiteContentDB = $site.ContentDatabase   

#Force delete site collection  
$SiteContentDB.ForceDeleteSite($Site.Id, $false, $false)  

2)In SharePoint 2016, only one attachment can be uploaded at a time, but you can add attachments multiple times.

3)Personal list view can be retained after migration.
