Hmm still strange ( yes was one third party when checked, but mentioned it).
If it works :
On question: YES, but you have to brave and willing to take some manual labour..
Backup your database(s) first, and save to pc) Log off for now.
Use a good editor (Notepad++ or PSPad or alike).
Now assuming you have the old/original (full) also in backup : (and if it is a v2 dbase..the better). in case V1 !!!!! this will not be the best solution at first glance since structural change)...
Best to describe we are after is comparing the old one and the new one.. When you open one you will see parts that are 'block mode 'eg. Pieces that mention CREATE TABLE with info and Pieces with INSERT INTO.
Now when ALL THE SAME is installed (plugs/theme, you could forget about the CREATE part) and focus on the INSERT pieces.
The Insert pieces hold the 'content' in USE.. eg a page created, a position etc.. (short > the 'works').
Each INSERT line starts with table names > for dbase structure!! DO NOT change that at all.
FOCUS on the VALUE lines > they start with (1, number, bla bla, bla, bla,,.... these are the ones needed)
WARNING ! Watch the last CHARACTER on the LAST value line> it ALWAYS has to end with a ; (semicolon)!!
Now when ALL is installed the ABS SAME. you should see (dbase) the same structure, (although the NEW dbase should hold LESS values (from installment), but the structure is there. THIS would make it EASY by just moving the the values into that structured area. (fe. a fresh install with plugins installed (no further content) would make the ideal setting)
2 methods : a) you do it on server/database by inserting sql queries, or b) cut and paste on pc editor.
(PC) BEWARE copy ONLY the value lines starting with (1....... untill the end ; (semicolon) Paste this into the new dbase at the SAME position ( is a (1... present....OVERWRITE. NO duplicate allowed!!!!) save.. use (if done correctly you are able to upload the dbatabase for usage and the system should use it..( when somethings wrong you WILL notice it)... SO test and be sure...
At sql server it is more different...(but not that hard).
The same applies ALL has to be present.. by example : suppose you use the e107_news TABLE. (this applies for all THOSE tables that are changed, eg plugins,pages etc.....so do not change everything; only the ones needed..less labour))
You have now 2 choices : either ALL replace OR partial..
IF ALL IS THE SAME : DELETE the table completly (e107_news) ; than copy CREATE TABLE + INSERT TO completly (for e107_news table) and use sql querie insert (normaly tab 3 on sql server) and PASTE ALL inside the empty window save.. the TABLE + Content should be created.... (green V = great...errors are reported)
Adding a single value line is nearly the same procedure (No CREATE piece) , but than duplicate may NOT exist, and you have to be very carefull with the good coding + the last semicolon !!!
Well a long story, maybe somewhat jibberish... but hey.. it does work. ALWAYS TEST before actual doing things.. Just do not forget..basically is copy and paste... just code use is tricky...
Need more info or help: be free to ask.
