An update is required for threshold procedures used to archive audit segments.
If your previous installation used a threshold procedure, similar to this,
            execute the following to archive the 
sysaudits
            table:
INSERT MyPre15SysAuditHistoryTable SELECT * FROM
sysaudits_0n
        where 
n corresponds to the 
sysaudits table number 1–8 and 
MyPre15SysAuditHistoryTable is a table defined prior to Adaptive Server
            version 15.7 SP100, then you must alter 
MyPre15SysAuditHistoryTable to add a 
nodeid column
            using:
alter table MyPre15SysAuditHistoryTable 
    add nodeid tinyint NULL
See the Reference Manual: Tables for system tables for
details about the sysaudits tables.
