Hello MOSIP Community, I’m planning a MOSIP implementation with focus on **Pre-Registration and Registration Client** customization, and need guidance on version selection. **Project Overview:** - **Goal:** Customize and deploy enrollment modules (Pre-Registration & Registration Client) - **Project Steps:** Phase 1: Installation and deployment on VPS for client demo Phase 2: Customization according to client needs Phase 3: Production deployment **Version Analysis:** I’m evaluating three versions: **v1.2.0** (LTS) - Stable and well-documented - Older release **v1.2.0.1** - Latest stable release - Java 11 - Proven in production **v1.2.1.0** - [Announcement](https://community.mosip.io/t/release-announcement-mosip-v1-2-1-0-is-here/2476) - Major Production Release - Java 21 migration - Better performance and security **Concerns about v1.2.1.0:** 1. **Version numbering confusion:** 2. **Known Issues (11 documented):** **My Questions:** **1. Which version should I use: v1.2.0 vs v1.2.0.1 vs v1.2.1.0?** **2. Why are modules versioned v1.3.0 for platform v1.2.1.0? Which tags should I use when cloning repositories if you recommend v1.2.1.0?** **3. For my first setup (Demo), do you recommend pulling images directly from mosipid?** Any guidance from the community or MOSIP team would be very helpful! Thank you. ---

Hello MOSIP Community, I previously shared my questions about choosing the right MOSIP version and setup for Pre-Registration and Registration Client, but I haven’t received any response yet. I would really appreciate any guidance on version selection and best practices for a first deployment and customization. ---

Hello @Oumaima_Laghjibi **1. Which version should I use: v1.2.0 vs v1.2.0.1 vs v1.2.1.0?** Please note the registration-client is not yet released as part of java21 migration release. So we suggest you to use the latest stable release [GitHub - mosip/registration-client at v1.2.0.2](https://github.com/mosip/registration-client/tree/v1.2.0.2) **2. Why are modules versioned v1.3.0 for platform v1.2.1.0? Which tags should I use when cloning repositories if you recommend v1.2.1.0?** For registration-client kindly use - v1.2.0.2 tag, for other modules please check the MOSIP docs release section to check the latest (patch) version for java21 migrated modules. Note, 1.2.0.2 reg-client is compatible with java21 migrated platform modules. **3. For my first setup (Demo), do you recommend pulling images directly from mosipid?** Yes, always. Thanks & Regards, MOSIP Team ---
