相信很多人都做过这样的操作，在Server 9.3.1 的时候发布了一个切片服务，然后升级到了Server10，升级后使用旧版本发布的切片服务，或者在另一台新机器上使用这些切片，我们完全不必重新将地图切一次，我们可以继续使用以前切好的地图切片，操作也很容易，只需要随便发布一个地图服务，定义切片的结构，也就是生成切片的缓存方案XML文件（当然要和以前的切片结构是一样的），然后用以前的切片直接覆盖到新的切片目录中对应的目录。
升级到ArcGIS 10.1 for Server可不可以这样做呢，我们知道ArcGIS 10.1 在发布服务的时候其实是用的是msd文档，是用该文档在发布的时候进行很多验证措施，比如空间参考，标注等。
我们发布地图不能像以前那样随便发布一个MXD文档，因为可能通不过验证。其次ArcGIS Server 10.1 目录结构是有变化的，在10.1 中切片是放在 /home/Soft/ArcGIS/server/arcgis/server/usr/directories/arcgiscache（我用的Linux系统，如果是windows系统，则切片路径在定义的缓存路径下，如D:\arcgisserver\directories\arcgiscache）中的，比如我发布的服务的名称是PointsofInterest，该服务的切片路径是PointsofInterest/home/Soft/ArcGIS/server/arcgis/server/usr/directories/arcgiscache/PointsofInterest/Layers，该目录下的文件如下图：
-alllayers目录中是存储切片的目录，而conf.xml文件是该切片服务的描述文件，里面包含切片级别，切片大小，空间参考等信息，conf.cdi文件是10.0增加的，该文件其实也是一个xml文件，里面包含了地图范围，空间参考，切片原点等信息，而Status.gdb是10.1增加的，是一个文件数据库，该数据库中存储了切片的状态信息，比如哪一个级别切片完了，哪一个级别正在切割，以及每一个级别的切片个数和大小，这个我们对我们了解整个切片是有很大的帮助意义的，下图是PointsofInterest的状态：
按照以前的做法，用已有的切片去覆盖现有的，我在ArcMap中将原来的图添加进来，看到的效果如下(上面的是替换后我新加的服务，下面的是原来的服务）
我们看到两个范围，大小都不能完全重合，这说明如果在10.1中直接覆盖或者替换切片是有问题的，原因在什么地方呢？
在10.1中，服务的切片有自己的存放位置，同时相应的服务也有自己的存储位置，服务的存储位置在配置的config-store下面，如我的服务的存储位置如下：/home/Soft/ArcGIS/server/arcgis/server/usr/config-store/services，而每一个服务在该目录下都有一个单独的文件夹，如PointsofInterest.MapServer，该文件夹中含有该服务的一些重要文件，如下图：
lock结尾的文件是锁文件我们不理会，json结尾的文件里面包含了该服务所使用的数据源，服务的地址等信息，具体信息如下所示：

这个配置文件的信息指向了一个MSD文档 位置为Z:\\home\\Soft\\ArcGIS\\server\\arcgis\\server\\usr\\directories\\arcgissystem\\arcgisinput\\PointsofInterest.MapServer\\extracted\\v101\\PointsofInterest.msd，而这个文档使用的数据/home/Soft/ArcGIS/server/arcgis/server/usr/directories/arcgissystem/arcgisinput/PointsofInterest.MapServer/extracted/v101,这个目录下有一个gdb的数据库，所以这个msd的数据的范围就来自这里（到这里我们可以知道和一个切片服务相关的目录有这些：
Services目录，arcgissystem\arcgisinput目录和Cache目录）。按照这个推理，我自己创建了一个要素类，画了几个多边形，发布服务，替换切片，结果又不能让人满意，因为地图服务可以重合但是范围小了，于是我打开这个/extracted/v101目录下的数据跟地图服务叠加，效果如下：
我们知道ArcGIS 10.1 for Server在发布数据的时候会copy原来数据库中的数据（如果注册了就不用了），Copy后自己重新计算了要素类的范围。
现在原因算是找到了，如果将这个服务的范围修改为跟要替换的切片是一样的，应该就不会有问题。将原先的切片加载到ArcMap中，创建一个范围大小和这个一样的要素类（点，先，面）都可以，我这里用的是面数据，创建后的要素类如下：
然后将这个要素类发布服务，在发布的时候，选择定义好的的切片结构，然后选择手动切片，如下图：
这样发布之后然后替换切片目录即可。效果如下图：
通过上面的分析要在10.1中使用早先已经切好的切片，我们用与该切片数据源范围必须一致的数据做地图文档，发布，然后切片，然后替换这样就OK了，那我如何得到原来图的范围呢，10.0的时候我们可以将所有的切片作为一个栅格数据加进来，创建一个等范围的要素类，然后发布服务，然后替换，现在大家知道如何做了吧？
