Not yet but we definitely have ideas for this coming up next on the roadmap.
The basic idea would be to allow you to create CAs with external/imported CA options which would assist with a migration.
For example, you would be able to "import" in a signed certificate (+chain) from an external parent CA when installing an intermediate CA in Infisical — As you'd expect, Infisical would generate a CSR for the CA to be signed by the parent CA externally.
We’ve been using Algora at https://trigger.dev for a while now. Other than being great for bountying issues we’ve found it especially helpful for getting video walkthroughs of our onboarding created and improving our docs.
We don’t have a newsletter at the moment so the best way to stay up to date is via Discord where we’ll be posting all our updates: https://discord.gg/hYmCPJRDcb
