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 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.
+@arv-copy@ allows users to copy collections, workflow definitions and projects from one cluster to another.
-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.
+For projects, @arv-copy@ will copy all the collections workflow definitions owned by the project, and recursively copy subprojects.
-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@.
+For workflow definitions, @arv-copy@ will recursively go through the workflow and copy all associated dependencies (input collections and Docker images).

+For example, let's copy from the <a href="https://playground.arvados.org/">Arvados playground</a>, also known as *pirca*, to *dstcl*. The names *pirca* and *dstcl* are interchangable with any cluster id. You can find the cluster name from the prefix of the uuid of the object you want to copy. For example, in *zzzzz*-4zz18-tci4vn4fa95w0zx, the cluster name is *zzzzz* .
-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.
+In order to communicate with both clusters, you must create custom configuration files for each cluster. The "Getting an API token":{{site.baseurl}}/user/reference/api-tokens.html page describes how to get a token and create a configuration file. However, instead of "settings.conf" in @~/.config/arvados@ you need two configuration files, one for each cluster, with filenames in the format of *ClusterID.conf*.
-<notextile>
-<pre><code>~$ <span class="userinput">cd ~/.config/arvados</span>
-~$ <span class="userinput">echo "ARVADOS_API_HOST=qr1hi.arvadosapi.com" >> qr1hi.conf</span>
-~$ <span class="userinput">echo "ARVADOS_API_TOKEN=123456789abcdefghijkl" >> qr1hi.conf</span>
-~$ <span class="userinput">echo "ARVADOS_API_HOST=dst_cluster.arvadosapi.com" >> dst_cluster.conf</span>
-~$ <span class="userinput">echo "ARVADOS_API_TOKEN=987654321lkjihgfedcba" >> dst_cluster.conf</span>

+In this example, navigate to the *Current token* page on each of *pirca* and *dstcl* to get the @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@.
-Now you're ready to copy between *qr1hi* and *dst_cluster*!
+The config file consists of two lines, one for ARVADOS_API_HOST and one for ARVADOS_API_TOKEN:

+ARVADOS_API_HOST=zzzzz.arvadosapi.com
+ARVADOS_API_TOKEN=v2/zzzzz-gj3su-xxxxxxxxxxxxxxx/123456789abcdefghijkl
+</pre>
-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/...@)
+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. In our example, you need two files, @~/.config/arvados/pirca.conf@ and @~/.config/arvados/dstcl.conf@.
-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 <a href="https://cloud.curoverse.com/collections/qr1hi-4zz18-tci4vn4fa95w0zx">lobSTR v.3 project on cloud.curoverse.com</a>.

+Now you're ready to copy between *pirca* and *dstcl*!
-The output of arv-copy displays the uuid of the collection generated in the destination cluster. By default, the output is placed in your home project in the destination cluster. If you want to place your collection in 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.
+h3. How to copy a collection
-For example, this will copy the collection to project dst_cluster-j7d0g-a894213ukjhal12 in the destination cluster.
+First, determine the uuid or portable data hash 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 *pirca* to *dstcl*. We will use the uuid @jutro-4zz18-tv416l321i4r01e@ as an example. You can find this collection on <a href="https://playground.arvados.org/collections/jutro-4zz18-tv416l321i4r01e">playground.arvados.org</a>.

-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.
+The output of arv-copy displays the uuid of the collection generated in the destination cluster. By default, the output is placed in your home project in the destination cluster. If you want to place your collection in an existing project, you can specify the project you want it to be in using the tag @--project-uuid@ followed by the project uuid.
-If you would like to copy the object without dependencies, you can use the @--no-recursive@ tag.
+For example, this will copy the collection to project @dstcl-j7d0g-a894213ukjhal12@ in the destination cluster.
-For example, we can copy the same object using this tag.

+Additionally, if you need to specify the storage classes where to save the copied data on the destination cluster, you can do that by using the @--storage-classes LIST@ argument, where @LIST@ is a comma-separated list of storage class names.
