我创建了一个农场功能，然后对其进行了升级。
根据文档，upgrade-spfeature -scope 场将升级所有需要升级的功能。功能升级（第 5 部分）——使用 PowerShell 升级功能（本文）
我只想升级一个，而且必须使用 PowerShell。
任何想法？
解决方案
im presuming that the feature is in a wsp so you should be able to do this:
Update-SPSolution –Identity YourSolutionName.wsp –LiteralPath “C:\YourSolutionName.wsp” –GacDeployment
http://technet.microsoft.com/en-us/library/ff607724.aspx
EDIT
forgot to mention you need to change the version number ;) for a more finer detail you can follow this:
1.Open the Feature Designer for Feature2. In the Properties pane, set the version number to 1.0.0.0. Where no version number is specified, a default of 0.0.0.0 is assumed. Version numbers must contain four components.
2.From the Build menu, select Deploy. This will deploy our version 1 solution to the farm.
3.In the Feature Designer, click the Manifest button at the bottom of the page. Expand the Edit Options section to display the Manifest Template. Replace the template XML with the following:
<?xml version="1.0" encoding="utf-8" ?>
<Feature xmlns="http://schemas.microsoft.com/sharepoint/">
<UpgradeActions>
<VersionRange>
<CustomUpgradeAction Name="MyUpgrade"/>
</VersionRange>
</UpgradeActions>
</Feature>
By attaching this XML to the feature definition, we’re defining the steps that should be taken to upgrade existing features. The CustomUpgradeAction element specifies that we’re using a feature receiver to perform the upgrade programmatically. In this example, we haven’t specified a version range, so this upgrade action will apply for all versions. If we needed to include different upgrade actions for different versions we could add this:
<Feature xmlns="http://schemas.microsoft.com/sharepoint/">
<UpgradeActions>
<VersionRange BeginVersion="1.0.0.0" EndVersion="2.0.0.0">
<CustomUpgradeAction Name="V2Upgrade"/>
</VersionRange>
<VersionRange BeginVersion="2.0.0.0" EndVersion="3.0.0.0">
<CustomUpgradeAction Name="V3Upgrade"/>
</VersionRange>
</UpgradeActions>
</Feature>
4.In the Properties pane, change the Version number for Feature 2 to 2.0.0.0.
Note
Within the Properties pane are options to set the Upgrade Actions Receiver Assembly and Class properties. These properties allow a feature to use a separate assembly for handling standard feature events such as Activate and Deactivate and a separate assembly for handling upgrade events. This facility is useful for retrofitting upgrade capabilities to a feature if the existing receiver assembly isn’t available or can’t be altered for some reason.
5.For the sake of simplicity, we’ll implement our upgrade code in our existing feature receiver. In the Feature2.EventReceiver.cs file, add the following code:
Code View: Scroll / Show All
public override void FeatureUpgrading(
SPFeatureReceiverProperties properties,
string upgradeActionName,
IDictionary<string, string> parameters)
{
switch (upgradeActionName)
{
case "MyUpgrade":
if (properties.Feature.Parent is SPWeb)
{
SPWeb web = properties.Feature.Parent as SPWeb;
using (Stream s = properties.Definition.GetFile(
"FirstElement\\MyConfig.xml"))
{
using (XmlReader rdr = XmlReader.Create(s))
{
rdr.ReadToDescendant("List");
do
{
string listName = rdr.GetAttribute("name").ToString();
SPList myList = web.Lists.TryGetList(listName);
if (myList != null)
{
myList.Description += "- Updated";
myList.Update();
}
} while (rdr.ReadToNextSibling("List"));
}
}
}
break;
default:
break;
}
}
}
Notice the use of a switch block in this code snippet to handle the upgradeActionName. This value is specified in the Name attribute of the CustomUpgradeAction element in the feature manifest.
6.If we deploy our updated feature using Visual Studio, our existing version will be removed first, which will make it impossible to test our upgrade process. Instead, we’ll package our solution using Visual Studio and deploy it manually. From the Build menu, select Package.
7.To test our upgrade process quickly, we can use PowerShell to upgrade a single feature. Choose Start | SharePoint 2010 Management Shell, and then enter the following script:
update-spsolution -identity Example 19.wsp -literalpath c:\code\example19\→
example19\bin\debug\example19.wsp -gacdeployment
Note This command should be entered as a single line.
8.This command will upgrade the Example19 solution package to the latest version. We can confirm this by entering the following script:
$featureName="Example19_feature2"
$latestVersion=(get-spfeature|where {$_.DisplayName -eq $featureName}).Version
$web=get-spweb http://<your Server Name>/example19
$theFeature=$web.Features|Where {$_.Definition.DisplayName -eq $featureName}
$currentVersion=theFeature.Version
write-host "Current Version: $currentVersion, Latest Version: $latestVersion"
If all is well, the resultant output should be this:
Current Version: 1.0.0.0, Latest Version: 2.0.0.0
9.We can upgrade a single feature using the following script:
$web=get-spweb http://<your Server Name>/example19
$theFeature=$web.Features|Where {$_.Definition.DisplayName -eq $featureName}
$theFeature.Upgrade($false)
10.Any errors that occur as part of the upgrade process will be shown in the PowerShell window. However, we can confirm that our upgrade was successful by issuing the following command:
write-host ($theFeature).Version
The new version number should be reported as 2.0.0.0.
其他提示
您可以在所需的spfeature对象上调用升级方法。 根据特征范围，您可能需要不同的代码来获取该SpFeature对象。
网站范围的示例：
$id = new-object System.Guid("<feature_id_here>")
$site = Get-SPSite "<site_url_here>"
$feature = $site.Features[$id]
$feature.Upgrade($false)
虽然Ali Jafer给出了一个非常全面的答案，但在我的情况下，使用要素名称的这些命令不起作用。我使用的功能ID，这里是我的powershell命令的样子。
Update-SPSolution –Identity "Example.wsp" –LiteralPath "E:\Visual Studio 2015\Projects\Example.wsp" –GacDeployment
$featureId = new-object System.Guid("FeatureID here")
$latestVersion=(get-spfeature|where {$_.Id -eq $featureId}).Version
$web=get-spweb "URL"
$theFeature=$web.Features|Where {$_.Definition.Id -eq $featureId}
$currentVersion=$theFeature.Version
write-host "Current Version: $currentVersion, Latest Version: $latestVersion"
$web=get-spweb "URL"
$theFeature=$web.Features|Where {$_.Definition.Id -eq $featureId}
$theFeature.Upgrade($false)
