Hi, I'd be happy to help you out with your question. Sorry for the inconvenience caused. Congratulations on your company merger. It feels like you've made good progress in migrating your AD objects and ensuring that your security groups, GPOs, and users are all up-to-date. To complete the merger with the new company, you'll need to make sure that their AD objects are also migrated and that any necessary updates or amendments are made to your existing infrastructure. Here are some additional steps you might want to consider: DNS integration: You'll need to integrate the DNS infrastructure of the new company with your existing DNS infrastructure so that all servers and workstations can communicate with each other. This means creating DNS zones and configuring DNS servers to provide name resolution for both companies. Exchange migration: If both companies are using Exchange servers for email, you'll need to plan and execute an Exchange migration. This involves migrating mailboxes, public folders, and other Exchange-related objects from the legacy Domain to your new Domain. Network integration: You'll need to make sure that the networks of both companies are integrated so that all users can access resources on both sides of the merger. This may involve reconfiguring firewalls, routers, and switches to allow traffic to flow between the two networks. File server consolidation: You may need to consolidate file servers from both companies into a single file server infrastructure. This involves moving data from the legacy Domain file servers to the new company's file servers or vice versa. Application integration: If both companies use different applications, you'll need to make sure that they are integrated so that users can access all necessary applications. This may involve updating application configurations, creating new application accounts, and configuring application permissions. Active Directory cleanup: As part of the merger, it's a good idea to clean up your AD environment. This involves identifying and removing any unused or unnecessary objects, such as stale user accounts, empty security groups, and unused GPOs. These are just some of the steps you might need to take when completing a company merger. I recommend working closely with your IT team and the new company's IT team to ensure that all necessary steps are taken and that the migration process goes smoothly. If you have any other questions or need assistance with anything, please don't hesitate to let me know. I'm here to help.
