Hi, as discussed on our Webinar just couple of days ago, we are publishing for your usage the migration tool. Please, download, try it, post some ideas how you would change it and.... change it! Because it's open source and open code 
Before you try it out, I would like to remind you few key assumptions that we put for it:
Scope
- Convert the most frequently used formulas in formula reports to V12 formulas
- Alea formulas (DBGET, DBGETC, DBSET, AT.GET, AT.HEAD, DE.NAME) -> first to OfficePlus, then to V12
- OfficePlus formulas (CELL.GET, CELL.GETC, CELL.WRITE, MEMBER.ANAME, MEMBER.MNAME) -> directly to V12
- Handle nested formulas (IF,...), strings within formulas, named ranges
- Convert all worksheets in all open workbooks at a time, so be careful what you have open when you try it.
- Write log info (warnings, errors) into a new worksheet
But also remember limitations:
- It’s not an official product, so share your comments here, not in support portal.
- No Ad Hoc reports, formula reports only
- No migration of modeling functions (e.g., DE.ADD)
- Source file must be .xlsx or .xlsm format and saved locally (not in repository)
- Tool is a VBA macro and requires 32-bit Excel (because it uses the "ALEA - VBA for Excel" library)
- Only default hierarchies support with hierarchies' names equal to dimensions' names
- Not designed for large Excel Reports (> 200 MB)
Please, also check full recording of the event from Tuesday here - https://pages.infor.com/20210413-hfe-pm-webinar-d-EPM-v-12-webinar-series-part5.html (recording and Q&A might be not available if you check it at the time of publishing this post, it will be there a little bit later)
The tool is available for download here - OfficePlus to Excel Integration migration tool
