I've had success with following the below steps to manually copy a form from one process to another. Of course that standard caveats apply about making sure to backup and thoroughly test before using in a production environment.

Objective:

Manually copy a Laserfiche form from 1 business process to another. (With the Forms UI there's no method to copy forms between business processes.) For the steps below BusinessProcessA will be the target process the form needs copied into and BusinessProcessB will be the source process the form will be copied from.

Optional preparation (this isn’t mandatory but does help streamline the other steps)

Prepare an optimized version of the source process (BusinessProcessB - the one the form will be copied out of) by exporting it and importing back in to a copy called BusinessProcessBOptimized

• Within the new optimized copy
  • remove all objects in the process map except the starting task and an ending task
  • remove all forms except the one that needs to be copied
  • remove all variables except the ones used by the form
• Use the new BusinessProcessBOptimized process in place of the BusinessProcessB for all steps below

Form Copy Steps:

1. Using the Laserfiche Forms "Manage" tab download the 2 target processes that will need a form copied between
   • The download will produce an XML file for each process
2. Open both of the XML files in your programming text editor of choice (preferably one that can navigate XML)
3. In the BusinessProcessB source file:
   • Navigate the XML tree to this node: "/businessprocess/Processes/Process/forms"
   • Once in the "forms" node find the correct form to copy by checking the "Name" node directly under each "form" node
   • Highlight and copy the entire form node; starting with the open tag <form> and ending with the closing tag </form>
4. In the BusinessProcessA target file:
   • Navigate the XML tree to this node: "/businessprocess/Processes/Process/forms"
   • Once in the "forms" node find the closing forms tag </forms>
   • Right before the closing forms tag paste the copied XML snippet into the file
   • Navigate into the form node that was just copied to check this tag is set to “false” “/businessprocess/Processes/Process/forms/form/isTriggerForm”. This tag identifies the starting form and can conflict if there’s another starting form to begin with. If the form needs to be a starting form, import it first then reset it to the starting form via the UI.
5. In the BusinessProcessB source file:
   • Navigate the XML tree to this node: "/businessprocess/Processes/Process/variables".
   • Make sure to highlight and copy everything in the “variables” node.
   • Highlight and copy all “variable” nodes under the “variables” parent; everything between the open tag <variables> and the closing tag </variables>
6. In the BusinessProcessA target file:
   • Navigate the XML tree to this node: "/businessprocess/Processes/Process/variables".
   • Once in the "variables" node find the closing forms tag </variables>
   • Right before the closing variables tag paste the copied XML snippet into the file Note: If the target process has no variables, you may need to create the proper open and closing variables tags
7. Optionally use the editor's tools to validate the XML structure is correct
8. Save the BusinessProcessA XML file
9.  Using the Laserfiche Forms "Manage" tab (or Design tab) upload the edited BusinessProcessA file and step through the import wizard
10. Once imported the new business process will have the copied form in the forms list
11. Cleanup and test the form
