Hi Vra

Here Custom Object name is CopyToAccount__c fields are Opportunity__c and Account__c
 
public class CopyDataOpportunity {
    public static void copyAllDataWithBaseOfOpporunity(){
        List<CopyToAccount__c> copyToAccountList = new List<CopyToAccount__c>();
        List<CopyToAccount__c> copyToAccountListBYMap = new List<CopyToAccount__c>();//use to store map List
        /* Copy all opportunituy id relatated to copyTo Account Object in oppIdSet set */
        Set<Id> oppIdSet = new Set<id>();
        List<CopyToAccount__c> UpdateCopyList = new List<CopyToAccount__c>();
        Map<Id,List<CopyToAccount__c>> OppIdVSCopyListMap  = new Map<Id,  List<CopyToAccount__c>>();
        Map<Id,Id> OppIdVSAccIdMap = new Map<Id,Id>();
        
        List<Opportunity> oppList = new List<Opportunity>();
        copyToAccountList = [SELECT Name,
                             Opportunity__c,
                             Account__c
                             FROM CopyToAccount__c ];
        if(copyToAccountList.size() > 0){
            for(CopyToAccount__c CopyToAccountObj : copyToAccountList)
            {
                if (!OppIdVSCopyListMap.containsKey(CopyToAccountObj.Opportunity__c)) {
                    OppIdVSCopyListMap.put(CopyToAccountObj.Opportunity__c, new List <CopyToAccount__c>());
                }
                OppIdVSCopyListMap.get(CopyToAccountObj.Opportunity__c).add(CopyToAccountObj);
            }
           oppList = [SELECT Account.Id
                       FROM Opportunity
                       WHERE Id =: OppIdVSCopyListMap.keySet() ];
            if(oppList.size() > 0){
                
                for(Opportunity OppObj : oppList)
                {
                    if (!OppIdVSAccIdMap.containsKey(OppObj.Id)) {
                        OppIdVSAccIdMap.put(OppObj.Id, OppObj.Account.Id );
                    }
                }
                for(Id MapOppId : OppIdVSCopyListMap.keySet()){
                    
                    copyToAccountListBYMap = OppIdVSCopyListMap.get(MapOppId);
                    for(CopyToAccount__c ObjForCopyField : copyToAccountListBYMap)
                    {
                        ObjForCopyField.Account__c = OppIdVSAccIdMap.get(MapOppId);
                        UpdateCopyList.add(ObjForCopyField);
                    }
                }
                if(UpdateCopyList.size() > 0 ){
                    UPDATE UpdateCopyList;
                }
            }
        }
    }  
}



Hope this might helps...
