The answer to this question is the same as the answers to question Infopath change Publish Location, if we speak about unmodifiable and locked Sharepoint List Form type (according to compatibility in Form Options< Info < File, on ribbon of Infopath Designer 2010) and Main Data Source/Connection:
Though, I failed to apply any those approaches in case of a list containing lookup field(s) to other list(s):
- editing source filed fails completely for me (in case of a list with a lookup field)
- in case of using a list template as an STP file approach, created from template list looses lookup field(s) content
One of the obvious questions is the sense of Sharepoint List Form and how to create the Infopath forms if they cannot be deployed thereafter.
One of the possible workaround is manually laborious engagement of CAML templates though it is unrelated to (already existing) Sharpoint list forms...
Good luck! Share here your experience here, please!
