This tutorial describes how to copy Arvados objects from one cluster to another by using @arv-copy@.
h2. arv-copy
-@arv-copy@ allows users to copy collections, pipeline templates, and pipeline instances from one cluster to another. By default, @arv-copy@ will recursively go through a template or instance and copy all dependencies associated with the object.
+@arv-copy@ allows users to copy collections and pipeline templates from one cluster to another. By default, @arv-copy@ will recursively go through a template and copy all dependencies associated with the object.
-For example, lets copy from our beta cloud instance *qr1hi* to *dst_cluster*. The names *qr1hi* and *dst_cluster* are interchangable with any cluster name. You can find the cluster name by the prefix of the uuid of the object you want to copy or the prefix of the @ARVADOS_API_HOST@.
+For example, let's copy from the <a href="https://cloud.curoverse.com/">cloud instance *qr1hi*</a> to *dst_cluster*. The names *qr1hi* and *dst_cluster* are interchangable with any cluster name. You can find the cluster name from the prefix of the uuid of the object you want to copy. For example, in *qr1hi*-4zz18-tci4vn4fa95w0zx, the cluster name is qr1hi.
-In order for the clusters to be able to communicate with each other, you must create custom configuration files for both clusters. First, go to your Manage Account page in Workbench and copy the @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@ in both of your clusters. Then, create two configuration files, one for each cluster. The names of the files must have the format of <uuid_prefix>.conf. In our example, let's make two files, one for *qr1hi* and one for *dst_cluster*. From your *Manage account* page in *qr1hi* and *dst_cluster*, copy the @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@.
+In order to communicate with both clusters, you must create custom configuration files for each cluster. In the Arvados Workbench, click on the dropdown menu icon <span class="fa fa-lg fa-user"></span> <span class="caret"></span> in the upper right corner of the top navigation menu to access the user settings menu, and click on the menu item *Current token*. Copy the @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@ in both of your clusters. Then, create two configuration files, one for each cluster. The names of the files must have the format of *uuid_prefix.conf*. In our example, let's make two files, one for *qr1hi* and one for *dst_cluster*. From your *Current token* page in *qr1hi* and *dst_cluster*, copy the @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@.

+Copy your @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@ into the config files as shown below in the shell account from which you are executing the commands. For example, the default shell you may have access to is shell.qr1hi. You can add these files in ~/.config/arvados/ in the qr1hi shell terminal.

h3. How to copy a collection
-First, select the uuid of the collection you want to copy from the source cluster. The uuid can be found inside of a collection in the top left box, or from the URL bar (the part after @collections/...@)
+First, select the uuid of the collection you want to copy from the source cluster. The uuid can be found in the collection display page in the collection summary area (top left box), or from the URL bar (the part after @collections/...@)
-Now copy the collection from *qr1hi* to *dst_cluster*. We will use the uuid @qr1hi-4zz18-tci4vn4fa95w0zx@ as an example. You can find this collection in the lobSTR v.3 project on *qr1hi*.

-The output of arv-copy displays the uuid of the collection generated. By default, the output is placed in your home project in the destination cluster. If you want to place your collection inside of a pre-created project, you can specify the project you want it to be in using the tag @--project-uuid@ followed by the project uuid.

+New branches in the destination git repo will be created for each branch used in the pipeline template. For example, if your source branch was named ac21f0d45a76294aaca0c0c0fdf06eb72d03368d, your new branch will be named @git_git_qr1hi_arvadosapi_com_reponame_git_ac21f0d45a76294aaca0c0c0fdf06eb72d03368d@.
+
+By default, if you copy a pipeline template recursively, you will find that the template as well as all the dependencies are in your home project.
+
+If you would like to copy the object without dependencies, you can use the @--no-recursive@ tag.
+
+For example, we can copy the same object using this tag.

-By default, if you copy a pipeline instance recursively, you will find that the template as well as all the dependecies are in your home project.
+The name, description, and workflow definition from the original workflow will be used for the destination copy. In addition, any *locations* and *docker images* found in the src workflow definition will also be copied to the destination recursively.
+
+If you would like to copy the object without dependencies, you can use the @--no-recursive@ flag.
