We have WSP solution (.wsp file) running on SP2010. I did uploaded same solution to SP online O365 environment and activated it. Now while programmatically creating sub site using this template, it throws error as:“File or arguments not valid for site template '{GUID}#TemplateName'.Parameter name: WebTemplate0x8102009f”
How can I use SP2010 WSP solution on SP online (O365) environment? If there are any upgrade steps to follow, please let me know↧
