db2实例32位升级64位 求教

使用./db2iupdt -w 64 db2inst1后
$ db2level
DB21085I  Instance "db2inst1" uses "64" bits and DB2 code release "SQL08027"
with level identifier "03080106".
Informational tokens are "DB2 v8.1.1.128", "s061108", "U810098", and FixPak
"14".
Product is installed at "/usr/opt/db2_08_01".

#su - db2inst1

$db2start

数据库不能start


求教是什么原因

800建议

1.将数据export出来
2.重新创建64位的instance
3.把export数据load进去

不知道各位大大有谁做过,大概需要多长时间
现在的数据量在15g左右

下面是操作过程
请大大们帮忙看下
# pwd
/usr/opt/db2_08_01/instance
# ./db2iupdt -w 64 db2inst1

看db2diag.log

生产环境直接update呀，没干过，不过觉得800的办法应该可以，呵呵
