Bootstrap other pw installation?

[bernhard]

Hi guys,

Is it possible to bootstrap a different pw installation on the same server? I tried including the other index.php file like stated in the docs but got an error:

Cannot redeclare ProcessWireBootConfig index.php line 160

I want to migrate some data from one installation to another. I know Adrian's migration module but would love to try it by hand as this could be very useful for another project I'm working on

Thanks!

It would be neat to be able to instantiate another installation within current one and just gain access to its API, but that's not possible (yet). Multi-instance support is currently listed under ProcessWire 3.0 in the roadmap.

Currently your best bet would probably be using a migration tool or otherwise exporting the data first, and then importing it as a separate action, whether by using a migrator tool or case-by-case import/export scripts.

In some cases it also makes sense to create a wrapper script that bootstraps another installation and performs specific tasks on; you can then call this wrapper via exec(), shell_exec(), or any of the other program execution features of PHP. Said features are, of course, extremely dangerous if unsanitized params are passed through, but you probably already knew that

Thank you teppo that helps I will try your suggestion of executing a separate script and come back when it worked.

Sanitization is no issue as it is a one time migration done by me, thanks for the hint nevertheless

i had to do some code cleanup and therefore ended up doing it all by hand... boring but the best solution in this case
