Not only for Tally for any software only upgrade is possible but downgrade not possible. Because of advanced version shall contain the many features than older version which are not available in older version. So while we trying to downgrade such additional features in advance version shall not found in older version then software fails to convert that.
As well as every software company generally design their software as for conversion from older to new but not the vice-versa, because of the don't want to go for back and may not think like that also.
However contact tally solutions for your query then they may be help you suggest in this regards if possible.
Next question is whenever i tried to add digital signature while efiling from Income tax website, i have to put the digital signature in fakepath folder or something ?????
