I get Repository Locked when publishing my changes to Collaborate

• When I try to publish my changes to Collaborate it says Repository is Locked. Please contact owner of the organization.

To continue with Plastic SCM, you need to finalise the migration by clicking Migrate on the popup that you see when you open your project.

If you're on the supported Unity version, you'll be able to continue with the Plastic SCM plugin for Unity. The plugin's workflow is not much different from Collaborate and is built-in in the Editor.

If you're on an unsupported Unity version, you'll need to continue with the Plastic SCM client. Please find information below about how to get started with Plastic SCM client.

To get started with the Plastic SCM client, you need to download the client from here (Cloud Edition), install it and log in with your Unity ID account. After this, you'd be able to find your project in 'Repositories' from the left side menu. When you find it, you right-click on it -> Crate workspace for this repository. In a new popup, you'd need to choose a local folder where you want your repository to be downloaded and, after you create a local folder, you'll see a green button in the top-right corner offering you to update. After you click on it, you'll get your project's files to this local folder downloaded from Plastic SCM and will be ready to continue working.

If by that time you have some changes in your old project that was connected to Collaborate, I'd suggest copying your Assets and ProjectSettings folders from this project to the new Plastic SCM project. After this is done, you'll be able to delete the old Collaborate project from your local machine and continue with the Plastic SCM client. 

To learn more about the client, please have a look throw the following links.
