Company Acquisition Checklist - DevOps part

During the last several years I had situations when our company acquired other startups and we had to take their infrastructure, code base, software over. I prepared a checklist which can help don’t forget some important parts, I hope it can be useful for you as well:

• Admin access to the code base: GitHub, Bitbucket, Gitlab, etc;
• CI/CD tools;
• Mail system, list of distribution email groups, passwords for important account;
• Hosting provider: Azure, Google, Amazon consoles, apps API keys;
• Apple Store, Google Play Developer accounts;
• SSH keys, credentials for servers;
• Reset 2FA, attached phone numbers to different consoles, accounts, get backup codes;
• Slack admin accounts or access to other chat system if needed;
• Company website hosting;
• Office network credentials;
• Long-term service contracts terms;
• Domains registrar. Validate that auto-pay and auto-renew configured, domains are locked;
