今天微软宣布了In-Place Upgrade 特性有一些改进。主要的一个是，现在用户能够通过In-Place Upgrade 改变虚拟机的规格，而不用重新部署整个服务。

我们以前所做的

在这个升级之前，由于虚拟机的规格是定义在CSDEF文件中，我们需要重新部署服务来改变VM Size属性。这意味着我们需要删除现有的角色和VMs，然后让Windows Azure重新分配新规格VMs、安装操作系统和运行时、提取和部署我们的应用程序。

改变虚拟机的规格是按比例增加和减少的最普遍的需求，不应该导致服务不可用。但是在Windows Azure里，我们要使用重新部署，不能让服务在那一刻能够访问。

我们现在所能做的

让我们看看我们需要做什么来改变虚拟机的规格而不用重新部署服务。首先，我们需要通过developer portal创建一个托管服务。然后，在Visual Studio里创建一个新的Windows Azure项目。让我们添加一个ASP.NET MVC 3 Web Role，将VM Size设置到Extra Small。然后将这个项目部署到Windows Azure。

我们在Visual Studio中将VM Size从Extra Small改变为Small并创建一个新的包。在那之后我们回到developer portal并使用In-Place Upgrade 来上传那个新包。在In-Place Upgrade对话框里我们需要勾选“Allow VM size or role count to be updated”，否则升级将会失败。

与不改变VM Size相比，这个升级需要花更多的时间，因为Fabric Controller需要找到一个合适的机器来托管该应用程序。这需要花费更多的时间，更重要的是，通过In-Place Upgrade改变VM
Size将删除原来虚拟机上所有自定义的数据。

通过In-Place Upgrade我们还可以做什么

不仅是改变VM Size，现在我们能添加和删除角色，改变端口号，并通过In-Place Upgrade增加本地存储容量。例如，在Visual Studio里添加一个新的Worker Role并在MVC 3 Web Role上向8080中添加一个新的输入端。

然后封装和使用In-Place Upgrade上传到托管服务。正如你所看到的，新角色和终端已经被建立了。

PS：别忘了勾选 “Allow VM size or role count to be updated”。

我为什么要使用In-Place Upgrade

In-Place Upgrade使得我们能够在升级期间确保服务的正常运行和有效性。不同于重新部署，如果一个角色拥有不止一个实例，它将通过在每个升级区域中轮流进行操作，从而在In-Place Upgrade的整个过程中可用。例如，如果一个web角色拥有2个Small虚拟机实例，当我们将它设为Extra Small，一次只能改变一个实例，然后在它完成后，才能改变其他的实例。

接下来

据说在接下来发布的版本里，我们可以在Visual Studio里直接进行更多的操作而不用转到developer portal。那时候程序开发人员在Visual Studio里就能完成整个部署任务了。

希望有所帮助，

Shaun

The input and output can be one of the following: - The path of a tileset JSON file - The path of a directory that contains a 'tileset.json' file - The path of a '.3tz' file - The path of a '.3dtiles' file The input can also be the path of a ZIP file that contains the tileset data. The tileset JSON file in this ZIP is determined by the 'inputTilesetJsonFileName', which is 'tileset.json' by default. glbToB3dm Repackage the input glb as a b3dm with a basic header. glbToI3dm Repackage the input glb as a i3dm with a basic header. b3dmToGlb Extract the binary glTF asset from the input b3dm. i3dmToGlb Extract the binary glTF asset from the input i3dm. cmptToGlb Extract the binary glTF assets from the input cmpt. splitCmpt Split the input cmpt and write out its inner tiles. convertB3dmToGlb Convert a b3dm file into a glTF asset that uses glTF extensions to represent the batch- and feature table information convertPntsToGlb Convert a pnts file into a glTF asset that uses glTF extensions to represent the point properties and batch- and feature table information convertI3dmToGlb Convert an i3dm file into a glTF asset that uses glTF extensions to represent the batch- and feature table information. This conversion may be lossy if the GLB of the input i3dm contains animations. optimizeB3dm Pass the input b3dm through gltf-pipeline. To pass options to gltf-pipeline, place them after --options. (--options -h for gltf-pipeline help) optimizeI3dm Pass the input i3dm through gltf-pipeline. To pass options to gltf-pipeline, place them after --options. (--options -h for gltf-pipeline help) updateAlignment Update the alignment of the batch- and feature table and the tile dataas a whole, to meet the alignment requirements of the specification. This can be applied to B3DM, I3DM, PNTS, or CMPT tile data. gzip Gzips the input tileset directory. ungzip Ungzips the input tileset directory. combine Combines all external tilesets into a single tileset.json file. merge Merge any number of tilesets together into a single tileset. mergeJson Merge any number of tilesets together into a single tileset without copying resources to output directory. upgrade Upgrades legacy tilesets to comply to the 3D Tiles specification. By default, this will upgrade legacy tilesets to comply to 3D Tiles 1.0. These upgrades include: - The asset version will be set to '1.0' - Content that uses a 'url' will be upgraded to use 'uri'. - The 'refine' value will be converted to be in all-uppercase. - glTF 1.0 models in B3DM or I3DM will be upgraded to glTF 2.0. When specifying '--targetVersion 1.1', then the upgrades will include: - The asset version will be set to '1.1' - Content that uses a 'url' will be upgraded to use 'uri'. - The 'refine' value will be converted to be in all-uppercase. - The '3DTILES_content_gltf' extension declaration will be removed. - PNTS, B3DM, and I3DM content will be converted to glTF. pipeline Execute a pipeline that is provided as a JSON file analyze Analyze the input file, and write the results to the output directory. This will accept B3DM, I3DM, PNTS, CMPT, and GLB files (both for glTF 1.0 and for glTF 2.0), and write files into the output directory that contain the feature table, batch table, layout information, the GLB, and the JSON of the GLB tilesetToDatabase Create a sqlite database for a tileset. (Deprecated - use 'convert' instead) databaseToTileset Unpack a tileset database to a tileset folder. (Deprecated - use 'convert' instead) createTilesetJson Creates a tileset JSON file that just refers to given tile content files. If the input is a single file, then this will result in a single (root) tile with the input file as its tile content. If the input is a directory, then all content files in this directory will be used as tile content, recursively. The exact set of file types that are considered to be 'tile content' is not specified, but it will include GLB, B3DM, PNTS, I3DM, and CMPT files. Options: --version Show version number [boolean] -h, --help Show help [boolean] -f, --force Output can be overwritten if it already exists. [boolean] [default: false] --logLevel The log level. Valid values are 'trace', 'debug', 'info', 'warn', 'error', 'fatal', and 'silent' [string] [default: "info"] --logJson Whether log messages should be printed as JSON instead of pretty-printing [boolean] [default: false] Unknown arguments: i, o, lasTo3dtiles

本方案是因为在工作中遇到的一个mysql主从功能配置的问题所引起的。有一个处在从位置上的mysql是5.1版本的，从5.1到5.6的mysql各种系统管理功能，像系统表表结构、日志文件格式等等均不一致。这时直接以5.1版本去作为一个5.6版本mysql的从时，会发现连binlog日志都解析失败了。于是评估各种利弊后，决定升级5.1的数据库版本至5.6.26 。 拿mysql5.1作为5.
