We are using Gitlab version 13.2.3 and would like to move to the latest version 13.12.2. As per documentation I see is that I will need to install each and every version in between. Is that true? or that is true only if you want no downtime? . We are okay with downtime. Can I install 13.12.3 directly on top or do we need to apply other patches in between. Any help is appreciated in this regard.
Also , if I need to setup a Test environment ( since we have just 1 environment (prod)) , is there any documentaion for this? Any recommendations on this.
