Installing Gitora and Formspider in the same database is possible. But you have to be a little bit careful.
For example, Gitora comes with its own Formspider runtime. So when you install Gitora, the installer first installs Formspider. At this point, the installer will point your public API synonyms to the Gitora installation. You should revert them back to your original Formspider installation.
There are other things that you have to be careful as well. For example, if you are using Formspider’s version control system in the database as well, accidentally you may put the same database object to two different version control systems at the same time. And that’s probably not something you want to do.
Technically, there are other options to use Gitora and Formspider together. For example, Gitora can be installed into your current Formspider schema. Both can point to the same Git installation to avoid the caveat I mentioned above. But the Gitora installer is not capable of doing these other setup options.
The instructions we send with the Formspider Upgrade Scripts also explain how to manually install Formspider Version Control. The same principles and steps explained in those instructions apply to manual Gitora installation as well. So you can follow them to customize your Gitora installation.
