There is an XF importer add-on which support IPS 4.x.
Many of our customers feel comfortable using the importer themselves and we also have a dedicated import support forum where you can post for assistance.
With new XF versions on the horizon, checking for above. Need to make a decision to convert 2 sites to XF or not. Both heavily use IPS downloads, so want to check, if it can be converted to XF resources or not? Thanks
