Update symbol from library not working

Question

I have a symbol drawn in `/path/to/symbol.dra` and the corresponding `/path/to/symbol.psm` file. This symbol was included in my `/path/to/main.mcm` design earlier. Now I modified `symbol.dra` and also the corresponding `symbol.psm`. I want this change to be updated in all instances of this symbol in `main.mcm`. I went to `Place/Update symbols` but it does not work. 
 If I do `Place/Manually/Advanced settings/List construction` and uncheck `database` and check `library`, Allegro finds `symbol` but with the old design. If I copy-paste `/path/to/symbol.psm` into `/path/to/symbol_deleteme.psm`, now this new symbol is found by Allegro and it has the modifications. Why does it fail if I don't change the name?

Seem there is a mismatch between pin number of component from schematic (or netlist) and pcb sumbol so it cna not be used. Correct schematic or pcb footprint is order to have same pin numbers in both side

Seems something is not understood. 
 A pcb footrpint have a definiton. Say for exemple SO14 
 A schematic symbol have a defintion. Say for exemple 7400 and is linked to SO14 footprint. 
 If pins are defined 1-14 on schematic side then the relted footprint shall use 1-14 for pin numbers. No less, no more. 
 Yo can not use a 1-16 pin footprint inked to 1-14 schematic symbol. 
 If footprint is already used for an other schematic symbol sucessfully, then do not chagne it: it will not work anymore with this one. 
 If schemaic symbol have diffrent pin numbering, then you have to use footpint with the new pin numbering (and maybe create it) 
 Tip: if you have a pcb footprint (the symbol, not associated to a component) placed on pcb side and change the pin definition, you have to update it BEFORE reading the netlist so at reading time it will be ok. If not updated, while reading netlist the tool see pin definiton from schematic different from footprint aleady present and can not associate.

I think this is the same issue as your ' Add footprint ' posting... 
 your library location `/path/to' is not shown in the entries for PSMPATH or PADPATH
