+
+#### Summary
+HCC will be retiring the $COMMON filesystem on July 1st, 2025 and powering it off shortly after.
+
+**Important Dates:**
+
+ - Common retired on July 1st, 2025
+
+
+#### Where can I move my data? 
+
+You can move your data to [NRDStor]({{< relref "../handling_data/data_storage/NRDSTOR/" >}}), or [Attic]({{< relref "../handling_data/data_storage/using_attic/" >}}). In any case, please make sure you have your important data backed up in another location. For large data transfers, it is strongly encouraged to use [Globus]({{< relref "../handling_data/data_transfer/globus_connect/" >}}) to transfer your data. The Globus transfer servers for Swan, and Attic provide a faster connection for the data transfer and provide checks on both ends of the data transfer. NRDStor is accessible from the Swan Globus Collection using the `/mnt/nrdstor/` path. 
+
+The retirement of Common also provides a good opportunity for researchers to evaluate and archive data that is no longer being used.  
+
+#### When is the data stored on Common going away?
+
+Data on Common will be removed shortly after the retirement on July 1st, 2025.  
+
+#### How do I get access to NRDStor?
+
+{{% notice warning %}}
+For those who are not a part of the University of Nebraska system, please contact hcc-support@unl.edu for instructions. 
+
+For those from the UNL, UNO, UNK, or UNMC campus, please follow the steps below.
+{{% /notice %}}
+
+[NRDStor]({{< relref "../handling_data/data_storage/NRDSTOR/" >}}) does not have immediate access to everyone with an HCC account. 
+The steps to get access are: 
+
+1. Complete the ["Introduction to NRDStor" course](https://nebraska.bridgeapp.com/learner/courses/21f78713/enroll).
+   
+2. [Request NRDStor Access](https://hcc.unl.edu/request-nrdstor-access)
+   
+3. Wait for the HCC group owner to approve of the request.
+   
+Once the HCC group owner has approved the request, HCC will grant access to NRDStor. After access has been granted, please review the [NRDStor Documentation.]({{< relref "../handling_data/data_storage/NRDSTOR/" >}}) 
+
+#### How can I migrate my data from Common to NRDstor or Attic?
+
+ - The first step will be to [log into Globus](https://app.globus.org/) using your University credentials or your Globus account. 
+ - [Activate the hcc#swan Globus collection](https://hcc.unl.edu/docs/handling_data/data_transfer/globus_connect/activating_hcc_cluster_endpoints/) and sign in using your HCC account. 
+ - Activate the collection for your destination, hcc#swan or hcc#attic for Swan and Attic respectively. 
+ - [In the "File Manager" tab in Globus](https://hcc.unl.edu/docs/handling_data/data_transfer/globus_connect/file_transfers_between_endpoints/), select the files and directories on the $COMMON side that you wish to transfer to NRDStor or Attic. NRDStor is accessible from the Swan Globus Collection using the `/mnt/nrdstor/` path.
+ - Click on the "Start" button above your files on NRDStor to initiate the copy. 
+    - The transfer will automatically start in the background across HCC's transfer servers. 
+
+We also have a brief overview of the use of Globus from a prior workshop available [here](https://youtu.be/7zhjr35ellI?t=1643).
+
+#### I use $COMMON in my submit scripts, what should I do now?
+All your submit scripts should be modified to not use $COMMON anymore, but the directory where your moved data is stored instead. Additionally, the required line #SBATCH --licenses=common in your submit scripts should be removed as well.
+
+#### Will my Globus Collection on a directory under $COMMON continue to be active?
+No, when $COMMON is retired the storage media will be immediately erased, and any access to data in $COMMON will be lost. Before the retirement of $COMMON, please move your data elsewhere and create a new Globus Collection following the steps [here](https://hcc.unl.edu/docs/handling_data/data_transfer/globus_connect/file_sharing/).
+
+#### Our group has shared directory on $COMMON, what should we do?
+Please contact hcc-support@unl.edu to have this directory moved to $WORK or $NRDSTOR. Please note that in order to use $NRDSTOR you need to first request access to it.
+
+#### How can I move my conda environment from $COMMON?
+For how to move and recreate existing conda environment, please see [here](https://hcc.unl.edu/docs/applications/user_software/using_anaconda_package_manager/#moving-and-recreating-existing-environment).
+
+#### Can I run jobs from $NRDSTOR?
+Yes, you can submit jobs from the $NRDSTOR file-system. Please note that the $WORK file-system is recommended for running jobs as a high-performance directory.
