OXE R6.2 (CPU7) to R12.2(CPU8) FAILED INTOF

[doublevand981]

Hi alll

I upgraded OXE from R.6.1 to R12.3 .
i did " fichges force_recover_dico" as the guide in TCxxx befor backup data base

but facing problem with remote shelfs. Some remote shelf could not sync with Local shelfs through INTOF2 card (just waitlink, Regi not INIT.) . before update these shelfs worked well.

i tried to backup and reload database, but some shelf fixed, some shelfs still error.

pls advise me some guide to check and fix this problem

Thanks so much
