Migrating from Moss 2007 to SharePoint 2013

Question

I am reaching out here as we require some inputs around migrating the SharePoint based application from MOSS 2007 to 2013.Please find more details from below
Requirement:
Migrating SharePoint site collection (which contains just 1 Top level site and 2 libraries with in it and no item level/library level permissions exists) which is on MOSS 2007 with size of 500GB to SharePoint 2013, hence we like to know your inputs in related
to this
Note:
1) The site collection has its own separate content database
2) There are nearly 200 thousand documents where the document with higher version is 90
3) The documents are stored in the libraries with up to third level of folder structure
4) The site collection is created based on custom site definition (created using visual studio)
Few things that I like to mention/ask here
a) Having 500GB data in one single content database inj the MOSS 2007 environment does it impacts the site performance?
b) Migrating the site collection as is  onto single content database (all 500 GB into one content database) into destination SharePoint 2013, does it will be a good practice? Hope SharePoint 2013 content database limit is 200 GB, hence moving 500GB
as is into one database will it be good practice?
c) Does database attach and detach works for the databases which are of size 500GB?
d) Can we do database attach and detach directly from MOSS 2007 to directly onto SharePoint 2013, without hopping onto SharePoint 2010 in between and then later to SharePoint 2013?
e) If moving 500GB data into one content database will not be a good approach, can we split it onto multiple databases?
f) If database attach and detach doesn’t help for databases which are of size 500GB, should we go for any tool based approach? If yes, which tool does best fit?

Answer 1

a) Having 500GB data in one single content database inj the MOSS 2007 environment does it impacts
the site performance?
Inder: Yes, it will impact site performance at large extended, recommended is 200 gb only. Check it IO of your disk to analyze performance issue
b) Migrating the site collection as is  onto single content database (all 500 GB into one content
database) into destination SharePoint 2013, does it will be a good practice? Hope SharePoint 2013 content database limit is 200 GB, hence moving 500GB as is into one database will it be good practice?
Inder: 
Content database size (all usage scenarios)
4 TB per content database
Supported
Content databases of up to 4 TB are supported when the following requirements are met:
Disk sub-system performance of 0.25 IOPs per GB. 2 IOPs per GB is recommended for optimal performance.
You must have developed plans for high availability, disaster recovery, future capacity, and performance testing.

c) Does database attach and detach works for the databases which are of size 500GB?
Inder: Yes it does work
d) Can we do database attach and detach directly from MOSS 2007 to directly onto SharePoint 2013, without
hopping onto SharePoint 2010 in between and then later to SharePoint 2013?
Inder: No, you need to pass through 2010 and then 2013
e) If moving 500GB data into one content database will not be a good approach, can we split it onto
multiple databases?
Inder: you can go with 500 gb
f) If database attach and detach doesn’t help for databases which are of size 500GB, should we go for
any tool based approach? If yes, which tool does best fit
